[PATCH 0/3] ASoC: mt6358: Fixes from an initial glance at a kselftest run

[Mark Brown]

This is a collection of fixes I came up after glancing through an
initial test run with the snappily named Kukui Jacuzzi SKU16 Chromebook
on KernelCI.  There are more issues flagged, this is just what I fixed
thus far.

[PATCH 1/3] ASoC: mt6358: Fix event generation for wake on voice stage 2 switch

[Mark Brown]

ALSA control put() operations should return 0 if the value changed so that
events can be generated appropriately for userspace but the custom control
for wake on voice stage 2 doesn't do this, fix it.

[PATCH 2/3] ASoC: mt6358: Validate Wake on Voice 2 writes

[Mark Brown]

Currently the Wake on Voice 2 control accepts and stores any value written
but it reports that only 0 and 1 are valid values. Reject any out of range
values written by userspace.

[PATCH 3/3] ASoC: mt6358: Remove undefined HPx Mux enumeration values

[Mark Brown]

The HPx Mux enumerations define values 5, 6 and 7 but describe them as
"undefined" and map them to the value 0 on writing. Given the descriptions
and behaviour it seems that these values are invalid and should not be
present in the register, the current behaviour is detected as problematic
by mixer-test:

# # HPL Mux.0 expected 5 but read 0, is_volatile 0
# # HPL Mux.0 expected 6 but read 0, is_volatile 0
# # HPL Mux.0 expected 7 but read 0, is_volatile 0

Remove the values from the enumeration, this will prevent userspace setting
them.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
