Two merge conflicts between this material and the mainline have
emerged since v6.15.

I've resolved them (they appear to be straightforward to me), but I
would appreciate double checking the most recent pm-cpufreq merge into
linux-next:

https://web.git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/commit/?h=linux-next&id=25eb7dda15f182b7355488a5aca47078643633dc

and letting me know if it looks good.

Thanks!
