[alsa-devel] [PATCH v2 0/5] max9867 driver update
Hi Mark,
this is yet another round of driver update. Tested on AT91SAM9G20 based board with codec in master mode. All implemeted controls do work now. Comments from previous serie taken into account.
Ladislav Michl (5): ASoC: max9867: Remove useless assignment ASoC: max9867: Fix power management ASoC: max9867: Calculate LRCLK divider ASoC: max9867: Fix signal paths ASoC: max9867: Add copyright and module author
ret is assigned later, no need to initialize it. --- sound/soc/codecs/max9867.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-)

The patch
ASoC: max9867: Remove useless assignment
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
