[pull] ttm drm-fixes-5.4

[Christian König]

Hi Dave, Daniel,

we had some problems this cycle sending out TTM fixes because of lack of 
time to rebase amd-staging-drm-next.

Because of this Alex and I decided that I'm going to send out TTM pull 
requests separately now. So this is the first small bunch of fixes for 5.4.

The following changes since commit 54ecb8f7028c5eb3d740bb82b0f1d90f2df63c5c:

   Linux 5.4-rc1 (2019-09-30 10:35:40 -0700)
