Linux drm/xe GPU kernel driver (display opregion): A resource leak in the xe driver's display opregion handling

Impact

A resource leak in the xe driver's display opregion handling. xe is the newer Intel GPU driver that Data Center GPU Max and later parts move to, so this is worth tracking as the xe driver takes over from i915 in production images.

Who can reach it

Local, on driver load/unload cycles.

What to do

Fix ships in the Linux kernel. Update the kernel and reboot the node - in practice this is a drain plus reboot because the accelerator driver cannot be unloaded while jobs hold device file descriptors. No BIOS or firmware update needed.
