[PATCH 0/7] ASoC: Mark expected switch fall-throughs

[Gustavo A. R. Silva]

Hi all,

In preparation to enabling -Wimplicit-fallthrough, this patchset aims
to add some annotations in order to mark switch cases where we are
expecting to fall through.

Thanks

Applied "ASoC: omap-dmic: Mark expected switch fall-throughs" to the asoc tree

[Mark Brown]

The patch

   ASoC: omap-dmic: Mark expected switch fall-throughs

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
