This commit seems to breaking a couple of devices with the Phoenix APU, most notably the Ryzen AI chips. Note that this commit in mainline seems to work as intended, and after doing a little bit of digging, [1] landed in 6.15 and so this cherrypick may not be so trivial after all. Attached is a kernel trace highlighting the breakage caused by this commit, along with [2] for the full log.

Also adding Alex, David and Mario to Ccs.
