[PATCH] ASoC: fsl_audmix: make clock and output src write only

From: Viorel Suman <redacted>

"alsactl -f state.conf store/restore" sequence fails because setting
"mixing clock source" and "output source" requires active TDM clock
being started for configuration propagation. Make these two controls
write only so that their values are not stored at "alsactl store".

      commit: 944c517b8c838832a166f1c89afbf8724f4a6b49

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
