Merge tag 'asoc-fix-v6.9-rc6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v6.9 This is much larger than is ideal, partly due to your holiday but also due to several vendors having come in with relatively large fixes at similar times. It's all driver specific stuff. The meson fixes from Jerome fix some rare timing issues with blocking operations happening in triggers, plus the continuous clock support which fixes clocking for some platforms. The SOF series from Peter builds to the fix to avoid spurious resets of ChainDMA which triggered errors in cleanup paths with both PulseAudio and PipeWire, and there's also some simple new debugfs files from Pierre which make support a lot eaiser.
