[alsa-devel] Applied "ASoC: rt5651: Do not modify jd and PLL power bits from set_bias_level()" to the asoc tree

[Mark Brown]

The patch

   ASoC: rt5651: Do not modify jd and PLL power bits from set_bias_level()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Subject: [PATCH] ASoC: rt5651: Do not modify jd and PLL power bits from
 set_bias_level()

rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire
register, including the jack-detect and PLL power bits. When jack-detection
support was introduced a special case for jack-detect was added which
hard-codes a register value to keep both on.

This commit removes the jack-detect special case, instead simply leaving
these bits as is on BIAS_OFF.
