Merge tag 'asoc-fix-v4.16-rc5' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v4.16 This is a fairly standard collection of fixes, there's no changes to the core here just a bunch of small device specific changes for single drivers plus an update to the MAINTAINERS file for the sgl5000.
