The SDCA class driver currently expects the device will be fully powered
down on system suspend but not on runtime suspend. This is typically
required as when audio is not active (ie. runtime suspend) jack detect
is expected to still function, but when the whole system is hibernated
there is no need to recognise audio jack events. This means the class
driver needs to always be informed of a system suspend, so the direct
complete optimisation (where PM will skip calling system suspend if the
device is runtime suspended) is not appropriate for the SDCA class
driver.
Add the NO_DIRECT_COMPLETE flag to prevent this optimisation from
running against this driver.

Adds test cases for getting a Dell SSIDExV2 string by calling
cs_amp_devm_get_vendor_specific_variant_id().
This is a fairly simple test harness, the redirected call to
cs_amp_get_efi_variable() returns a test string to simulate
reading a string from UEFI. The returned string should be
the second field in the SSIDExV2 string (if valid).

If cs_amp_devm_get_vendor_specific_variant_id() returns a string, use it
as part of the firmware filename. If this firmware isn't found, fall back
to the standard firmware name.
This re-uses the fwf_suffix fallback mechanism that was introduced in
commit e5d5b3aebd ("ASoC: cs35l56: Use SoundWire address as alternate
firmware suffix on L56 B0").
This is for handling vendors that use the same PCI SSID on systems with
various audio hardware and have a custom vendor-specific way to identify
the hardware variant.
This is currently used on Dell laptops. Dell create a UEFI variable that
indicates varations to the base hardware. This variance can be any part
of the hardware (not necessarily affecting the audio). It would be
impractical to publish many aliases for the same firmware files to match
every possible variance to that base hardware. Hence the fallback to the
standard firmware name. This allows alternate firmware files to be
published only for variants that need it. For all other variants the
fallback will load the firmware for the base SSID.
This is not done for CS35L56 B0 because the fallback mechanism is already
used for a different purpose for these parts. None of the products with
the older L56 B0 silicon revision need the additional vendor-specific
descriptor.
For SoundWire the resulting firmware searches with a variant descriptor
will be:
1. cs35l??-dsp1-misc-SSID-VARIANT-l?u?.wmfw
2. cs35l??-dsp1-misc-SSID-VARIANT.wmfw
3. cs35l??-dsp1-misc-SSID-VARIANT-l?u?.bin
4. cs35l??-dsp1-misc-SSID-VARIANT.bin
If this doesn't find a wmfw and bin file it will then fallback to:
5. cs35l??-dsp1-misc-SSID-l?u?.wmfw
6. cs35l??-dsp1-misc-SSID.wmfw
7. cs35l??-dsp1-misc-SSID-l?u?.bin
8. cs35l??-dsp1-misc-SSID.bin
With the typical published firmware names and qualifiers (a single wmfw but
amp-specific bin file) this will load either:
cs35l??-dsp1-misc-SSID-VARIANT.wmfw
and cs35l??-dsp1-misc-SSID-VARIANT-l?u?.bin
or
cs35l??-dsp1-misc-SSID.wmfw
and cs35l??-dsp1-misc-SSID-l?u?.bin
For non-Soundwire (I2S/TDM) systems the searches and fallbacks are
as above except that the "l?u?" component of the name is instead the
ALSA name prefix, usually of the form "AMPn".

Add a function cs_amp_devm_get_vendor_specific_variant_id() to return
a vendor-specific hardware identifier string (if there is one) and use
it to fetch an identifier from Dell SSIDExV2 UEFI variable content.
Dell use the same PCI SSID on multiple products that might have different
audio hardware and thus need different firmware for the amplifier DSP.
The SSIDExV2 string contains additional system identifiers, and the
second field is a 2-character audio hardware identifier.
There are older Dell models with Cirrus Logic amplifiers that have the
SSIDExV2 UEFI variable but do not have the 2-character audio ID in the
second field. The SSIDExV2 is ignored if the second field is not
2 characters.

Commit 962e8a01ea ("ext4: introduce mext_move_extent()") attempts to
call ext4_swap_extents() on the failure path to recover the swapped
extents, but fails to acquire locks for the two inode->i_data_sem,
triggering the BUG_ON statement in ext4_swap_extents().
This issue can be fixed by calling ext4_double_down_write_data_sem()
before ext4_swap_extents().

The padding at the end of struct ext4_tune_sb_params is architecture
specific and in particular is different between x86-32 and x86-64,
since the __u64 member only enforces struct alignment on the latter.
This shows up as a new warning when test-building the headers with
-Wpadded:
include/linux/ext4.h:144:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded]
All members inside the structure are naturally aligned, so the only
difference here is the amount of padding at the end. Make the padding
explicit, to have a consistent sizeof(struct ext4_tune_sb_params) of
232 on all architectures and avoid adding compat ioctl handling for
EXT4_IOC_GET_TUNE_SB_PARAM/EXT4_IOC_SET_TUNE_SB_PARAM.
This is an ABI break on x86-32 but hopefully this can go into 6.18.y early
enough as a fixup so no actual users will be affected. Alternatively, the
kernel could handle the ioctl commands for both sizes (232 and 228 bytes)
on all architectures.
