The in-tree 7.2 CVS driver we ship as the intel-cvs DKMS module requests its "wake" line with devm_gpiod_get(). On the Dell XPS 14 DA14260 that pin (\_SB.GPI1 20) is the shared GpioIo the four CS35L57 amplifiers read their speaker ID from, so with this package installed every cs35l56 probe fails with "error -EBUSY: Failed to get spk-id-gpios" and the machine has no sound card. Carry Junjie Cao's upstream fix, "media: i2c: cvs: Get the wake IRQ without claiming the GPIO" (Cc: stable, Fixes: 8e2b43d2c10b), applied to the downloaded intel-cvs-core.c in prepare(). makepkg symlinks plain downloads into srcdir and patch refuses symlinks, so the file is copied first. Drop the patch once the stable tag we fetch from contains the fix. Link: https://github.com/thesofproject/sof/issues/11152 Link: https://bugzilla.redhat.com/show_bug.cgi?id=2529031
