Putting a struct stmmac_rss object on the stack is a bad idea,

As the object is the trivial empty case, change the called function
to accept a NULL pointer to mean the same thing and remove the
large variable in the two callers.

Merge tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski:
"In this cycle we've finally managed to contribute the patch set
sorting out LED naming issues. Besides that there are many changes
scattered among various LED class drivers and triggers.
LED naming related improvements:
- add new 'function' and 'color' fwnode properties and deprecate
'label' property which has been frequently abused for conveying
vendor specific names that have been available in sysfs anyway
- introduce a set of standard LED_FUNCTION* definitions
- introduce a set of standard LED_COLOR_ID* definitions
- add a new {devm_}led_classdev_register_ext() API with the
capability of automatic LED name composition basing on the
properties available in the passed fwnode; the function is
backwards compatible in a sense that it uses 'label' data, if
present in the fwnode, for creating LED name
- add tools/leds/get_led_device_info.sh script for retrieving LED
vendor, product and bus names, if applicable; it also performs
basic validation of an LED name
- update following drivers and their DT bindings to use the new LED
registration API:
- leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
Other LED class improvements:
- replace {devm_}led_classdev_register() macros with inlines
- allow to call led_classdev_unregister() unconditionally
- switch to use fwnode instead of be stuck with OF one
LED triggers improvements:
- led-triggers:
- fix dereferencing of null pointer
- fix a memory leak bug
- ledtrig-gpio:
- GPIO 0 is valid
Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
more complete driver exists, based on a generic driver for the AMD
SOCs gpio-controller, supporting LEDs as well other devices:
- drop profile field from priv data
- drop iosize field from priv data
- drop enum_apu_led_platform_types
- drop superseeded apu2/3 led support
- add pr_fmt prefix for better log output
- fix error message on probing failure
Other misc fixes and improvements to existing LED class drivers:
- leds-ns2, leds-max77650:
- add of_node_put() before return
- leds-pwm, leds-is31fl32xx:
- use struct_size() helper
- leds-lm3697, leds-lm36274, leds-lm3532:
- switch to use fwnode_property_count_uXX()
- leds-lm3532:
- fix brightness control for i2c mode
- change the define for the fs current register
- fixes for the driver for stability
- add full scale current configuration
- dt: Add property for full scale current.
- avoid potentially unpaired regulator calls
- move static keyword to the front of declarations
- fix optional led-max-microamp prop error handling
- leds-max77650:
- add of_node_put() before return
- add MODULE_ALIAS()
- Switch to fwnode property API
- leds-as3645a:
- fix misuse of strlcpy
- leds-netxbig:
- add of_node_put() in netxbig_leds_get_of_pdata()
- remove legacy board-file support
- leds-is31fl319x:
- simplify getting the adapter of a client
- leds-ti-lmu-common:
- fix coccinelle issue
- move static keyword to the front of declaration
- leds-syscon:
- use resource managed variant of device register
- leds-ktd2692:
- fix a typo in the name of a constant
- leds-lp5562:
- allow firmware files up to the maximum length
- leds-an30259a:

The branch contains driver changes that are tightly
connected to SoC specific code. Aside from smaller
cleanups and bug fixes, here is a list of the notable
changes.
New device drivers:
- The Turris Mox router has a new "moxtet" bus driver
for its on-board pluggable extension bus. The
same platform also gains a firmware driver.
- The Samsung Exynos family gains a new Chipid driver
exporting using the soc device sysfs interface
- A similar socinfo driver for Qualcomm Snapdragon
chips.
- A firmware driver for the NXP i.MX DSP IPC protocol
using shared memory and a mailbox
Other changes:
- The i.MX reset controller driver now supports the
NXP i.MX8MM chip
- Amlogic SoC specific drivers gain support for
the S905X3 and A311D chips
- A rework of the TI Davinci framebuffer driver to
allow important cleanups in the platform code
- A couple of device drivers for removed ARM SoC
platforms are removed. Most of the removals were
picked up by other maintainers, this contains
whatever was left.

The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.
The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody is
using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still in
active use and are converted to the ARCH_MULTIPLATFORM build, meaning
that we can compile a kernel that works on these along with most other
ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
but additional work is needed to complete this. Patches for the
remaining ARMv5 platforms have started but need more work and some
testing.
Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.
Other changes include a cleanup of the ST-Ericsson ux500 platform
and the move of the TI Davinci platform to a new clocksource driver.

[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new
warnings that I most definitely do not want to see during the merge

ena_dev->intr_moder_rx/tx_interval save the intervals received from the
user after dividing them by ena_dev->intr_delay_resolution. Therefore
when intr_delay_resolution changes, the code needs to first mutiply
intr_moder_rx/tx_interval by the previous intr_delay_resolution to get
the value originally given by the user, and only then divide it by the
new intr_delay_resolution.
Current code does not first multiply intr_moder_rx/tx_interval by the old

There is a race condition that can occur when calling ena_down().
The ena_clean_tx_irq() - which is a part of the napi handler -
function might wake up the tx queue when the queue is supposed
to be down (during recovery or changing the size of the queues
for example) This causes the ena_start_xmit() function to trigger
and possibly try to access the destroyed queues.
The race is illustrated below:
Flow A: Flow B(napi handler)
ena_down()
netif_carrier_off()
netif_tx_disable()
ena_clean_tx_irq()
netif_tx_wake_queue()
ena_napi_disable_all()
ena_destroy_all_io_queues()
After these flows the tx queue is active and ena_start_xmit() accesses
the destroyed queue which leads to a kernel panic.

100GbE Intel Wired LAN Driver Updates 2019-09-12
This series contains updates to ice driver to implement and support

Paul updates the way the driver version is stored in the driver so that
we can pass the driver version to the firmware. Passing of the driver
version to the firmware is needed for the DDP package to ensure we have
the appropriate support in the driver for the features in the package.
Lukasz fixes how the firmware version is stored to align with how the

display additional useful information such as NVM version, API patch
information and firmware build hash.

Intel Wired LAN Driver Updates 2019-09-11
This series contains updates to i40e, ixgbe/vf and iavf.
Wenwen Wang fixes a potential memory leak where 3 allocated variables
are not properly cleaned up on failure for ixgbe.
Stefan Assmann fixes a potential kernel panic found when repeatedly
spawning and destroying VFs in i40e when a NULL pointer is dereferenced
due to a race condition. Fixed up the i40e driver to clear the
__I40E_VIRTCHNL_OP_PENDING bit before returning after an invalid
minimum transmit rate is requested. Updates the iavf driver to only
apply the MAC address change when the PF ACK's the requested change.
Tonghao Zhang updates ixgbe to use the skb_get_queue_mapping() API call
instead of the driver accessing the queue mapping directly.
Jake updates i40e to use ktime_get_real_ts64() instead of
ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud
filters, since it is a reserved bit and not a valid type. Also added
code comments to clearly state which bits are reserved and should not be
used or defined for cloud filter adminq command. Clarify the macros
used to specify the cloud filter fields are individual bits, so use the
BIT() macro.
Aleksandr fixes up the print_link_message() to include the "negotiated"
FEC status for i40e.
Czeslaw also adds additional log message for devices without FEC in the
print_link_message() for i40e.
Colin Ian King reduces the object code size by making the array API

Since the model number is purely used for reporting purposes, follow
the hardware team convention of subtracting 0x10 from the PluDevice

Tx code doesn't clear the descriptors' status after cleaning.
So, if the budget is larger than number of used elems in a ring, some
descriptors will be accounted twice and xsk_umem_complete_tx will move
prod_tail far beyond the prod_head breaking the completion queue ring.
Fix that by limiting the number of descriptors to clean by the number
of used descriptors in the Tx ring.
'ixgbe_clean_xdp_tx_irq()' function refactored to look more like
'ixgbe_xsk_clean_tx_ring()' since we're allowed to directly use
'next_to_clean' and 'next_to_use' indexes.

There were a couple cases where the ITR value generated via the adaptive
ITR scheme could exceed 126. This resulted in the value becoming either 0
or something less than 10. Switching back and forth between a value less
than 10 and a value greater than 10 can cause issues as certain hardware
features such as RSC to not function well when the ITR value has dropped
that low.

When the RX rings are created they are also populated with buffers
so that packets can be received. Usually these are kernel buffers,
but for AF_XDP in zero-copy mode, these are user-space buffers and
in this case the application might not have sent down any buffers
to the driver at this point. And if no buffers are allocated at ring
creation time, no packets can be received and no interrupts will be
generated so the NAPI poll function that allocates buffers to the
rings will never get executed.
To rectify this, we kick the NAPI context of any queue with an
attached AF_XDP zero-copy socket in two places in the code. Once
after an XDP program has loaded and once after the umem is registered.
This take care of both cases: XDP program gets loaded first then AF_XDP
socket is created, and the reverse, AF_XDP socket is created first,
then XDP program is loaded.

Currently iavf unconditionally applies MAC address change requests. This
brings the VF in a state where it is no longer able to pass traffic if
the PF rejects a MAC filter change for the VF.
A typical scenario for a rejected MAC filter is for an untrusted VF to
request to change the MAC address when an administratively set MAC is
present.
To keep iavf working in this scenario the MAC filter handling in iavf
needs to act on the PF reply regarding the MAC filter change. In the
case of an ack the new MAC address gets set, whereas in the case of a
nack the previous MAC address needs to stay in place.

To avoid this the call to i40e_sync_vsi_filters() in

which is also used by i40e_free_vfs().

In-between the MAC & PHY there can be a mode converter, which converts one
mode to another (e.g. GMII-to-RGMII).
The converter, can be passive (i.e. no driver or OS/SW information
required), so the MAC & PHY need to be configured differently.
For the `stmmac` driver, this is implemented via a `mac-mode` property in
the device-tree, which configures the MAC into a certain mode, and for the
PHY a `phy_interface` field will hold the mode of the PHY. The mode of the
PHY will be passed to the PHY and from there-on it work in a different
mode. If unspecified, the default `phy-mode` will be used for both.
