Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Add outer runtime_pm protection to xe_live_ktest@xe_dma_buf
Any kunit doing any memory access should get their own runtime_pm outer references since they don't use the standard driver API entries. In special this dma_buf from the same driver.
Found by pre-merge CI on adding WARN calls for unprotected inner callers:
