ASoC: Intel: bytcr_rt5640: Add quirk for ARCHOS Cesium 140
Tha ARCHOS Cesium 140 tablet has problem with the jack-sensing,
thus the heaset functions are not working.

Add quirk for this model to select the correct input map, jack-detect
options and channel map to enable jack sensing and headset microphone.
This device uses IN1 for its internal MIC and JD2 for jack-detect.

Srinivas Kandagatla 7e20ae1208
ASoC: q6afe-clocks: Add missing parent clock rate
setting clock rate on child clocks without a parent clock rate will
result in zero clk rate for child. This also means that when audio
is started dsp will attempt to access registers without enabling
clock resulting in board boot up.

Fix this by adding the missing parent clock rate.

ASoC: Intel: Boards: tgl_max98373: update TDM slot_width
Speaker amp's SSP bclk configuration was changed in the topology file to be
based on 12.288MHz and dai_ops->hw_params is based on s32le format.
But, the TDM slot size remained set to 24 bits.
This inconsistency created audible noises and needs to be corrected.
This patch updates TDM slot width to 32.

Takashi Iwai ab5893fdc0
ASoC: amd: Return -ENODEV for non-existing ACPI call
AMD Renoir driver tries to identify the presence of DMIC by evaluating
ACPI _WOV entry, and it returns -EINVAL when the ACPI call failed.
This ended up an error message like
  snd_rn_pci_acp3x: probe of 0000:04:00.5 failed with error -22
although the system is correctly set up.

For avoiding such a superfluous error message, change the return value
to -ENODEV.  Then the driver core just skips to the next one without
complaining.

Takashi Iwai 2509bb342e
ASoC: amd: Downgrade print level for invalid ACP mode
The acp3x raven driver skips the probing when the given device isn't
connected with I2S.  This skip behavior itself is fine, but the driver
also emits an error message "Invalid ACP audio mode" with KERN_ERR.
This isn't nice since it appears on the boot screen even if a boot
splash is running, although this itself is no real error.

Downgrade the print level to KERN_INFO so that this message won't
appear on the console unnecessarily.

ASoC: Intel: bytcr_rt5640: Fix HP Pavilion x2 Detachable quirks
The HP Pavilion x2 Detachable line comes in many variants:

1. Bay Trail SoC + AXP288 PMIC, Micro-USB charging (10-k010nz, ...)
   DMI_SYS_VENDOR: "Hewlett-Packard"
   DMI_PRODUCT_NAME: "HP Pavilion x2 Detachable PC 10"
   DMI_BOARD_NAME: "8021"

2. Bay Trail SoC + AXP288 PMIC, Type-C charging (10-n000nd, 10-n010nl, ...)
   DMI_SYS_VENDOR: "Hewlett-Packard"
   DMI_PRODUCT_NAME: "HP Pavilion x2 Detachable"
   DMI_BOARD_NAME: "815D"

3. Cherry Trail SoC + AXP288 PMIC, Type-C charging (10-n101ng, ...)
   DMI_SYS_VENDOR: "HP"
   DMI_PRODUCT_NAME: "HP Pavilion x2 Detachable"
   DMI_BOARD_NAME: "813E"

4. Cherry Trail SoC + TI PMIC, Type-C charging (10-p002nd, 10-p018wm, ...)
   DMI_SYS_VENDOR: "HP"
   DMI_PRODUCT_NAME: "HP x2 Detachable 10-p0XX"
   DMI_BOARD_NAME: "827C"

5. Cherry Trail SoC + TI PMIC, Type-C charging (x2-210-g2, ...)
   DMI_SYS_VENDOR: "HP"
   DMI_PRODUCT_NAME: "HP x2 210 G2"
   DMI_BOARD_NAME: "82F4"

Variant 1 needs the exact same quirk as variant 2, so relax the DMI check
for the existing quirk a bit so that it matches both variant 1 and 2
(note the other variants will still not match).

Variant 2 already has an existing quirk (which now also matches variant 1)

Variant 3 uses a cx2072x codec, so is not applicable here.

Variant 4 almost works with the defaults, but it also needs a quirk to
fix jack-detection, add a new quirk for this.

Variant 5 does use a RT5640 codec (based on old dmesg output), but was
otherwise not tested, keep using the defaults for this variant.

ASoC: Intel: catpt: Skip position update for unprepared streams
Playing with very low period sizes may lead to timeouts when awaiting
RESET_STREAM reply for offload streams. This is caused by NOTIFY_POSITION
appearing in the middle of trigger(stop).

Stream is unprepared during trigger(stop) where PAUSE_STREAM IPC gets
invoked. However, all data that is already mixed in DSP firmware's mixer
stream will still be played regardless of the pause. For offload streams,
this means possibility for another NOTIFY_POSITION to process. Keep these
notifications in check by only handling them when stream is in prepared
state.

Commit 453431a549 ("mm, treewide: rename kzfree() to
kfree_sensitive()") renamed kzfree() to kfree_sensitive(),
but it left a compatibility definition of kzfree() to avoid
being too disruptive.

Since then a few more instances of kzfree() have slipped in.

Just get rid of them and remove the compatibility definition
once and for all.

Joe Perches 0f7f635b06 checkpatch: enable GIT_DIR environment use to set git repository location
If set, use the environment variable GIT_DIR to change the default .git
location of the kernel git tree.

If GIT_DIR is unset, keep using the current ".git" default.

   introduce parisc specific wrappers for those syscalls which filter
   out the old O_NONBLOCK value and replaces it with the new one.

Linus Torvalds 91f28da8c9 random32: make prandom_u32() less predictable
This is the cleanup of the latest series of prandom_u32 experimentations
 consisting in using SipHash instead of Tausworthe to produce the randoms
 used by the network stack. The changes to the files were kept minimal,
 and the controversial commit that used to take noise from the fast_pool
 (f227e3ec3b) was reverted. Instead, a dedicated "net_rand_noise" per_cpu
 variable is fed from various sources of activities (networking, scheduling)
 to perturb the SipHash state using fast, non-trivially predictable data,
 instead of keeping it fully deterministic. The goal is essentially to make
 any occasional memory leakage or brute-force attempt useless.
 
 The resulting code was verified to be very slightly faster on x86_64 than
 what is was with the controversial commit above, though this remains barely
 above measurement noise. It was also tested on i386 and arm, and build-
 tested only on arm64.
 
 The whole discussion around this is archived here:

Hans de Goede 8058d69905 i2c: core: Restore acpi_walk_dep_device_list() getting called after registering the ACPI i2c devs
Commit 21653a4181 ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().

But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().

Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.

This fixes the Microsoft Surface Go 2 hanging at boot.

Fixes: 21653a4181 ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")
