4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Daniel Vetter <daniel.vet...@ffwll.ch> commit d3e376f52d095103ca51dbda4d6ff8aaf488f98f upstream. This is called without dev->struct_mutex held, we need to use the _unlocked variant. Never caught in the wild since you'd need an evil userspace which races a gem_close ioctl call with the in-progress open.
