Subject: [PATCH] ASoC: mxs-saif: Add variable dev to simplify code

Add variable 'dev' to make the code cleaner in the function
mxs_saif_probe(). And now that the function mxs_saif_mclk_init()
have defined the variables 'ret' as the error returned value,
then it should be used instead in this place.

I find it clearer to integrate such source code adjustments by separate patches
together with improved commit messages.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=1d2cc5ac6f6668cc15216d51051103c61467d7e8#n138


Would you become interested to search for similar update candidates
by the means of the semantic patch language (Coccinelle software)?

Regards,
Markus

Thanks!

[1/1] ASoC: mxs-saif: Add variable dev to simplify code
(no commit info)

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
