Merge tag 'asoc-fix-v5.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v5.1 A few core fixes along with the driver specific ones, mainly fixing small issues that only affect x86 platforms for various reasons (their unusual machine enumeration mechanisms mainly, plus a fix for error handling in topology). There's some of the driver fixes that look larger than they are, like the hdmi-codec changes which resulted in an indentation change, and most of the other large changes are for new drivers like the STM32 changes.
