[PATCH 1/2] ASoC: cs35l32: Delete two error messages for a failed memory allocation in cs35l32_i2c_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>

Omit extra messages for a memory allocation failure in this function.

This issue was detected by using the Coccinelle software.

Applied "ASoC: cs35l32: Delete two error messages for a failed memory allocation in cs35l32_i2c_probe()" to the asoc tree

[Mark Brown]

The patch

   ASoC: cs35l32: Delete two error messages for a failed memory allocation in cs35l32_i2c_probe()

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

[PATCH 2/2] ASoC: cs35l32: Improve two size determinations in cs35l32_i2c_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 22 Nov 2017 20:40:47 +0100

Replace the specification of two data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.
