Pulled out of the next patch to improve its legibility.
As the function is now available, call it directly from
snd_emu10k1_emu1010_init(), thus making the MicroDock firmware loading
synchronous - there isn't really a reason not to. Note that this does
not affect the AudioDocks of rev1 cards, as these have no independent
power supplies, and thus come up only a while after the main card is
initialized.
As a drive-by, adjust the priorities of two messages to better reflect
their impact.

While there are two separate IRQ status bits for dock attach and detach,
the hardware appears to mix them up more or less randomly, making them
useless for tracking what actually happened. It is much safer to check
the dock status separately and proceed based on that, as the old polling
code did.
Note that the code assumes that only the dock can be hot-plugged - if
other option card bits changed, the logic would break.

Drop the flow-hash of the skb when forwarding to the L2TP netdev.
This avoids the L2TP qdisc from using the flow-hash from the outer
packet, which is identical for every flow within the tunnel.
This does not affect every platform but is specific for the ethernet
driver. It depends on the platform including L4 information in the
flow-hash.
One such example is the Mediatek Filogic MT798x family of networking

[ Upstream commit 4b911a9690d72641879ea6d13cce1de31d346d79 ]
syzbot triggered various splats (see [0] and links) by a crafted GSO
packet of VIRTIO_NET_HDR_GSO_UDP layering the following protocols:
ETH_P_8021AD + ETH_P_NSH + ETH_P_IPV6 + IPPROTO_UDP
NSH can encapsulate IPv4, IPv6, Ethernet, NSH, and MPLS. As the inner
protocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), calls
skb_mac_gso_segment() to invoke inner protocol GSO handlers.
nsh_gso_segment() does the following for the original skb before
calling skb_mac_gso_segment()
1. reset skb->network_header
2. save the original skb->{mac_heaeder,mac_len} in a local variable
3. pull the NSH header
4. resets skb->mac_header
5. set up skb->mac_len and skb->protocol for the inner protocol.
and does the following for the segmented skb
6. set ntohs(ETH_P_NSH) to skb->protocol
7. push the NSH header
8. restore skb->mac_header
9. set skb->mac_header + mac_len to skb->network_header
10. restore skb->mac_len
There are two problems in 6-7 and 8-9.
(a)
After 6 & 7, skb->data points to the NSH header, so the outer header
(ETH_P_8021AD in this case) is stripped when skb is sent out of netdev.
Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH),
skb_pull() in the first nsh_gso_segment() will make skb->data point
to the middle of the outer NSH or Ethernet header because the Ethernet
header is not pulled by the second nsh_gso_segment().
(b)
While restoring skb->{mac_header,network_header} in 8 & 9,
nsh_gso_segment() does not assume that the data in the linear
buffer is shifted.
However, udp6_ufo_fragment() could shift the data and change
skb->mac_header accordingly as demonstrated by syzbot.
If this happens, even the restored skb->mac_header points to
the middle of the outer header.
It seems nsh_gso_segment() has never worked with outer headers so far.
At the end of nsh_gso_segment(), the outer header must be restored for
the segmented skb, instead of the NSH header.
To do that, let's calculate the outer header position relatively from
the inner header and set skb->{data,mac_header,protocol} properly.

[ Upstream commit 5bcf0dcbf9066348058b88a510c57f70f384c92c ]
When redirecting a packet using XDP, the bpf_redirect_map() helper will set
up the redirect destination information in struct bpf_redirect_info (using
the __bpf_xdp_redirect_map() helper function), and the xdp_do_redirect()
function will read this information after the XDP program returns and pass
the frame on to the right redirect destination.
When using the BPF_F_BROADCAST flag to do multicast redirect to a whole
map, __bpf_xdp_redirect_map() sets the 'map' pointer in struct
bpf_redirect_info to point to the destination map to be broadcast. And
xdp_do_redirect() reacts to the value of this map pointer to decide whether
it's dealing with a broadcast or a single-value redirect. However, if the
destination map is being destroyed before xdp_do_redirect() is called, the
map pointer will be cleared out (by bpf_clear_redirect_map()) without
waiting for any XDP programs to stop running. This causes xdp_do_redirect()
to think that the redirect was to a single target, but the target pointer
is also NULL (since broadcast redirects don't have a single target), so
this causes a crash when a NULL pointer is passed to dev_map_enqueue().
To fix this, change xdp_do_redirect() to react directly to the presence of
the BPF_F_BROADCAST flag in the 'flags' value in struct bpf_redirect_info
to disambiguate between a single-target and a broadcast redirect. And only
read the 'map' pointer if the broadcast flag is set, aborting if that has
been cleared out in the meantime. This prevents the crash, while keeping
the atomic (cmpxchg-based) clearing of the map pointer itself, and without
adding any more checks in the non-broadcast fast path.

[ Upstream commit 7f970ecb77b6759d37ee743fc36fc0daba960e75 ]
This moves the message state in the AXI SPI Engine driver to a new
struct spi_engine_msg_state.
Previously, the driver state contained various pointers that pointed
to memory owned by a struct spi_message. However, it did not set any of
these pointers to NULL when a message was completed. This could lead to
use after free bugs.
Example of how this could happen:
1. SPI core calls into spi_engine_transfer_one_message() with msg1.
2. Assume something was misconfigured and spi_engine_tx_next() is not
called enough times in interrupt callbacks for msg1 such that
spi_engine->tx_xfer is never set to NULL before the msg1 completes.
3. SYNC interrupt is received and spi_finalize_current_message() is
called for msg1. spi_engine->msg is set to NULL but no other
message-specific state is reset.
4. Caller that sent msg1 is notified of the completion and frees msg1
and the associated xfers and tx/rx buffers.
4. SPI core calls into spi_engine_transfer_one_message() with msg2.
5. When spi_engine_tx_next() is called for msg2, spi_engine->tx_xfer is
still be pointing to an xfer from msg1, which was already freed.
spi_engine_xfer_next() tries to access xfer->transfer_list of one
of the freed xfers and we get a segfault or undefined behavior.
To avoid issues like this, instead of putting per-message state in the
driver state struct, we can make use of the struct spi_message::state
field to store a pointer to a new struct spi_engine_msg_state. This way,
all of the state that belongs to specific message stays with that
message and we don't have to remember to manually reset all aspects of
the message state when a message is completed. Rather, a new state is
allocated for each message.
Most of the changes are just renames where the state is accessed. One
place where this wasn't straightforward was the sync_id member. This
has been changed to use ida_alloc_range() since we needed to separate
the per-message sync_id from the per-controller next available sync_id.

This modifies the AXI SPI Engine driver to use devm_spi_alloc_host()
instead of spi_alloc_host() to simplify the code a bit.
In addition to simplifying the error paths in the probe function, we
can also remove spi_controller_get/put() calls in the remove function
since devm_spi_alloc_host() sets a flag to no longer decrement the
controller reference count in the spi_unregister_controller() function.

Long ago a map file descriptor in a pseudo ldimm64 instruction could
only be present as an immediate value insn[0].imm, and thus this value
was used in a verbose verifier message printed when the file descriptor
wasn't valid. Since addition of BPF_PSEUDO_MAP_IDX_VALUE/BPF_PSEUDO_MAP_IDX
the insn[0].imm field can also contain an index pointing to the file
descriptor in the attr.fd_array array. However, if the file descriptor
is invalid, the verifier still prints the verbose message containing
value of insn[0].imm. Patch the verifier message to always print the
actual file descriptor value.

Add a regmap_read_bypassed() to allow reads from the hardware registers
while the regmap is in cache-only mode.
A typical use for this is to keep the cache in cache-only mode until
the hardware has reached a valid state, but one or more status registers
must be polled to determine when this state is reached.
For example, firmware download on the cs35l56 can take several seconds if
there are multiple amps sharing limited bus bandwidth. This is too long
to block in probe() so it is done as a background task. The device must
be soft-reset to reboot the firmware and during this time the registers are
not accessible, so the cache should be in cache-only. But the driver must
poll a register to detect when reboot has completed.

similarly due to no protection of saved_data_ready. Here is another
different caller causing the same issue because of the same reason. So
we should protect it with sk_callback_lock read lock because the writer

For all the "score" pin-groups all the intel_pingroup-s to select
the non GPIO function are re-used for byt_score_gpio_groups[].
But this is incorrect since a pin-group includes the mode setting,
which for the non GPIO functions generally is 1, where as to select
the GPIO function mode must be set to 0.
So the GPIO function needs separate intel_pingroup-s with their own mode
value of 0.
Add a new PIN_GROUP_GPIO macro which adds a foo_gpio entry to each
pin-group defined this way and update byt_score_gpio_groups[] to point
to the new foo_gpio entries.
The "sus" usb_oc_grp usb_ulpi_grp and pcu_spi_grp pin-groups are special
because these have a non 0 mode value to select the GPIO functions and
these already have matching foo_gpio pin-groups, leave these are unchanged.

There is a misinterpretation of some of the PIN_CONFIG_* options in this
driver library. PIN_CONFIG_OUTPUT_ENABLE should refer to a buffer or
switch in the output direction of the electrical path. The MediaTek
hardware does not have such a thing. The driver incorrectly maps this
option to the GPIO function's direction.
Likewise, PIN_CONFIG_INPUT_ENABLE should refer to a buffer or switch in
the input direction. The hardware does have such a mechanism, and is
mapped to the IES bit. The driver however sets the direction in addition
to the IES bit, which is incorrect. On readback, the IES bit isn't even
considered.
Ironically, the driver does not support readback for PIN_CONFIG_OUTPUT,
while its readback of PIN_CONFIG_{INPUT,OUTPUT}_ENABLE is what it should
be doing for PIN_CONFIG_OUTPUT.
Rework support for these three options, so that PIN_CONFIG_OUTPUT_ENABLE
is completely removed, PIN_CONFIG_INPUT_ENABLE is only linked to the IES
bit, and PIN_CONFIG_OUTPUT is linked to the GPIO function's direction
and output level.

In the generic pin config library, readback of some options are handled
differently compared to the setting of those options: the argument value
is used to convey enable/disable of an option in the set path, but
success or -EINVAL is used to convey if an option is enabled or disabled
in the debugfs readback path.
PIN_CONFIG_INPUT_SCHMITT_ENABLE is one such option. Fix the readback of
the option in the mediatek-paris library, so that the debugfs dump is
not showing "input schmitt enabled" for pins that don't have it enabled.

The "pctldev" struct is allocated in devm_pinctrl_register_and_init().
It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(),
so freeing it in pinctrl_enable() will lead to a double free.
The devm_pinctrl_dev_release() function frees the pindescs and destroys
the mutex as well.

This patch adds support for QCA2066 firmware patch and NVM downloading.
as the RF performance of QCA2066 SOC chip from different foundries may
vary. Therefore we use different NVM to configure them based on board ID.

- optimize the function qca_generate_hsp_nvm_name
- remove redundant debug code for function qca_read_fw_board_id

[ Upstream commit caba40ec3531b0849f44502a03117796e8c9f4a1 ]
The DDR3 SPD data structure advertises the presence of a thermal
sensor on a DDR3 module in byte 32, bit 7. Let's use this information
to explicitly instantiate the thermal sensor I2C client instead of
having to rely on class-based I2C probing.
The temp sensor i2c address can be derived from the SPD i2c address,
so we can directly instantiate the device and don't have to probe
for it. If the temp sensor has been instantiated already by other
means (e.g. class-based auto-detection), then the busy-check in
i2c_new_client_device will detect this.
Note: Thermal sensors on DDR4 DIMM's are instantiated from the
ee1004 driver.

The thread that calls the module initialisation code when a module is
loaded is not guaranteed [in fact, it is unlikely] to be the same one
that calls the module cleanup code on module unload, therefore, `Module`
implementations must be `Send` to account for them moving from one
thread to another implicitly.
