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:
