CVE-2026-31547

In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Fix missing runtime PM reference in ccsmodestore

ccsmodestore() calls xegtreset() which internally invokes xepmruntimegetnoresume(). That function requires the caller to already hold an outer runtime PM reference and warns if none is held:

[46.891177] xe 0000:03:00.0: [drm] Missing outer runtime PM protection [46.891178] WARNING: drivers/gpu/drm/xe/xepm.c:885 at xepmruntimeget_noresume+0x8b/0xc0

Fix this by protecting xegtreset() with the scope-based guard(xepmruntime)(xe), which is the preferred form when the reference lifetime matches a single scope.

v2: - Use scope-based guard(xepmruntime)(xe) (Shuicheng) - Update commit message accordingly
