Merge tag 'asoc-v6.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.7
More updates for v6,7 following the early merge request:
- Fixes for handling of component name prefixing when name prefixes
are used by the machine driver.
- Fixes for noise when stopping some Sounwire CODECs.
- Support for AMD ACP 6.3 and 7.0, Awinc AW88399, more Intel
platforms and more Qualcomm SC7180 platforms.
