[alsa-devel] [PATCH 0/4] ASoC: Intel: 4 small cleanups

[alsa-devel] [PATCH 0/4] ASoC: Intel: 4 small cleanups

[Hans de Goede]

Hi All,

Here are 4 ASoC/Intel cleanup patches, these were written to
get to know the kernel-devel process by a group of students
which I was coaching on a kernel project.

Their original submission needed some cleanup which they never
got around to. So I've done the cleanup now and I'm submitting
a cleaned-up version of the cleanup patches.

Regards,

Hans

[alsa-devel] [PATCH 1/4] ASoC: Intel: bytcr_rt5640: Remove code duplication in byt_rt5640_codec_fixup

[Hans de Goede]

From: Erik Bussing <eabbussing@outlook.com>

The 16 and 24 bit paths in byt_rt5640_codec_fixup are mostly identical,
introduce a local bits variable to address the only difference and move
the common bits out of the if ... else ... .

[alsa-devel] Applied "ASoC: Intel: bytcr_rt5640: Remove code duplication in byt_rt5640_codec_fixup" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: bytcr_rt5640: Remove code duplication in byt_rt5640_codec_fixup

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

[alsa-devel] [PATCH 2/4] ASoC: Intel: bytcr_rt5640: Remove unnecessary string buffers and snprintf calls

[Hans de Goede]

From: Nariman Etemadi <narimantos@gmail.com>

The snprintf calls filling byt_rt56*_codec_aif_name/byt_rt56*_cpu_dai_name
always fill them with the same string ("rt56*-aif2" resp. ssp0-port").
So instead of keeping these buffers around and making codecs->dai_name /
cpus->dai_name point to them, simply update the *->dai_name pointers to
directly point to a string constant containing the desired string.

[alsa-devel] Applied "ASoC: Intel: bytcr_rt5651: Remove unnecessary string buffers and snprintf calls" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: bytcr_rt5651: Remove unnecessary string buffers and snprintf calls

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: Intel: bytcr_rt5651: Remove unnecessary string buffers
 and snprintf calls

The snprintf calls filling byt_rt56*_codec_aif_name/byt_rt56*_cpu_dai_name
always fill them with the same string ("rt56*-aif2" resp. ssp0-port").
So instead of keeping these buffers around and making codecs->dai_name /
cpus->dai_name point to them, simply update the *->dai_name pointers to
directly point to a string constant containing the desired string.

around and making cpus->dai_name / codecs->dai_name point to this,
simply update the *->dai_name pointers to directly point to a string
constant containing the desired string.
