Technical description

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:
