The patch

   ASoC: rt5514-spi: Get the period_bytes in the copy work to make sure the value correctly

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.

to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: rt5514-spi: Get the period_bytes in the copy work to
 make sure the value correctly

The value of period_bytes will get the zero before the hw_params() is not
run completely. Move the function snd_pcm_lib_period_bytes() to copy work,
and make sure that is not zero.
