This series (and a related headphone codec fix) were merged into Linus's
tree yesterday.
I saw that the 6.7.4 stable patches were sent out for review over night,
but could it be possible to squeeze in also the following four fixes in
6.7.4 (and 6.6.16)?
c481016bb4f8 ASoC: qcom: sc8280xp: limit speaker volumes
4d0e8bdfa4a5 ASoC: codecs: wcd938x: fix headphones volume controls
46188db080bd ASoC: codecs: lpass-wsa-macro: fix compander volume hack
b53cc6144a3f ASoC: codecs: wsa883x: fix PA volume control
These are needed for proper volume control and, importantly, to prevent
users of the Lenovo ThinkPad X13s from potentially damaging their
speakers when the distros ship the latest UCM configuration files which
were released on Monday.
Johan
