Merge tag 'asoc-fix-v6.15-rc4' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v6.15 A moderately large batch of fixes for v6.15, many driver specific including cleanups for the enabling of the Cirrus KUnit tests and a fix for a nasty crash on resume on AMD systems. We also have one core fix, for an ordering issue between DAPM and DPCM which could leave things incorrectly unpowered.
