Merge tag 'drm-fixes-for-v4.15-rc5' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"I've got most of two weeks worth of fixes here due to being on
holidays last week.
The main things are:
- Core:
* Syncobj fd reference count fix
* Leasing ioctl misuse fix
- nouveau regression fixes
- further amdgpu DC fixes
- sun4i regression fixes
I'm not sure I'll see many fixes over next couple of weeks, we'll see
how we go"
