Merge tag 'asoc-fix-v5.18-rc3' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v5.18 A collection of fixes that came in since the merge window, plus one new device ID for an x86 laptop. Nothing that really stands out with particularly big impact outside of the affected device.
