Pull drm fixes from Dave Airlie:
"This might just be part one, but I'm sending it a bit early as it has
two sets of reverts for regressions, one is all the gem/dma-buf
handling and another was a nouveau ioctl change.
Otherwise there is an amdgpu fix, nouveau fix and a scheduler fix.
If any other changes come in I'll follow up with another more usual
Fri/Sat MR.
gem:
- revert all the dma-buf/gem changes as there as lifetime issues
with them
nouveau:
- revert an ioctl change as it causes issues
- fix NULL ptr on fermi
bridge:
- remove extra semicolon
sched:
- remove hang causing optimisation
amdgpu:
- fix garbage in cleared vram after resume"
