[PATCH v2 0/9] ASoC: codecs: qcom fix validation failures

[Srinivas Kandagatla]

Thanks for pointing out to mixer kselftest and VALIDATION Kconfig.

This patchset addresses some of the issues in Qualcomm codecs that are
discovered with recent mixer kselftest and validations added to ASoC.

Mostly these are under
1. accessing integer value type for enum controls, which is clearly an array out of bounds access.
2. Fix incorrect ranges.
3. Fix return values for put functions.

Changes since v1:
- removed tlv min max patches as "9bdd10d57a ("ASoC: ops:
Shift tested values in snd_soc_put_volsw() by +min")" fixed the issue in core.
- added checks in wcd934x_rx_hph_mode_put before returning

thanks,
srini

[PATCH v2 1/9] ASoC: codecs: rx-macro: fix accessing compander for aux

[Srinivas Kandagatla]

AUX interpolator does not have compander, so check before accessing
compander data for this.

Without this checkan array of out bounds access will be made in
comp_enabled[] array.

The unconditional change notifications are present in this patch and
I'm guessing some others as well (they were there in a bunch
previously):

[PATCH v2 5/9] ASoC: codecs: wsa-macro: fix accessing array out of bounds for enum type

[Srinivas Kandagatla]

Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes.

Also fix return value of put function, so that change notifications are
sent correctly.

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

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
