Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "This feels larger than I'd like but its for three reasons.

   a) amdkfd finalising the API more, this is a new feature introduced
      last merge window, and I'd prefer to make the tweaks to the API
      before it first gets into a stable release.

   b) radeon regression required splitting an internal API to fix
      properly, so it just changed a few more lines

   c) vmwgfx fix changes a lock from a mutex->spin lock, this is fallout
      from the new sleep checking.

  Otherwise there is just some tda998x fixes"
