Guys, I don't think this commit is right; I've had 2 out of three resume 
failures since this change went into Linus' master. I've attached a 
pstore dump of the latest crash, and while it appears to be coming from 
the Intel XE driver, 95% of my (s0ix) resumes worked previously[1] 
before this change.

LMK if you need more information.

[1] - unless I forget to detach my NVMe USB4 external drive before 
suspending, which is a breakage that appears to have gone in sometime 
around the 6.10 series, but I haven't been able to bisect it
