The patch

   ASoC: rt5651: Make rt5651_apply_properties() private

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.

Subject: [PATCH] ASoC: rt5651: Make rt5651_apply_properties() private

The idea behind exporting rt5651_apply_properties(), was for it to be used
on platforms where the platform code may need to add device-properties,
rather then relying only on properties set by the firmware. The platform
code could then call rt5651_apply_properties() after adding properties to
make sure that the codec driver was aware of the new properties.

But this is not necessary, as long as we do all property parsing from
the codec component-driver's probe function (or later) then the machine
driver can attach properties before calling snd_soc_register_card and
calling rt5651_apply_properties() for ordering reasons is not necessary.

This commit makes rt5651_apply_properties() private and adds 2 comments
documenting that all property parsing must be done from the codec
component-driver's probe function.
