Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Fix GEM free for imported dma-bufs
Imported dma-bufs also have obj->resv != &obj->_resv. So we should
check both this condition in addition to flags for handling the
_NO_SHARE case.
Fixes this splat that was reported with IRIS video playback:
