ASoC: ssm2518: Use a signed return type for ssm2518_lookup_mcs()

From: Markus Elfring <[email protected]>
Date: Sun, 20 Dec 2015 10:34:25 +0100

The return type "unsigned int" was used by the ssm2518_lookup_mcs() function even though it will eventually return a negative error code. Improve this implementation detail by deletion of the type modifier then.

This issue was detected by using the Coccinelle software.

The patch

ASoC: ssm2518: Use a signed return type for ssm2518_lookup_mcs()

has been applied to the asoc tree at

git://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
