Merge tag 'asoc-fix-v4.14-rc7' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v4.14 A bunch of fixes here, mostly device specific ones (the biggest one being the revert of the hotword support for rt5514), with a couple of core fixes for potential issues with corrupted or otherwise invalid topology files.
