Currently the check against the max value for the control is being
applied after the value has had the minimum applied and been masked. But
the max value simply indicates the number of volume levels on an SX
control, and as such should just be applied on the raw value.

Fixes: e9b397afabb8 ("ASoC: ops: Check bounds for second channel in snd_soc_put_volsw_sx()")

Sigh, sorry about that will send a new version.

Thanks,

[2/2] ASoC: cs42l51: Correct PGA Volume minimum value
      commit: 3d1bb6cc1a654c8693a85b1d262e610196edec8b

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
