Merge tag 'asoc-fix-v5.16-rc3' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v5.16
There's a large but repetitive set of fixes here for issues with the
Tegra kcontrols not correctly reporting changes to userspace, a fix for
some issues with matching on older x86 platforms introduced during the
merge window together with a set of smaller fixes and one new system
quirk.
