[PATCH] ASoC: arizona: Don't change the FLLn_GAIN before entering FREERUN

[Charles Keepax]

From: Nariman Poushin <nariman@opensource.wolfsonmicro.com>

When reclocking an active FLL, to ensure a clean transition, do
not change the gain setting until we have entered free run.

The patch

   ASoC: arizona: Don't change the FLLn_GAIN before entering FREERUN

has been applied to the asoc tree at

   git://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

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.
