Merge branch 'vmwgfx-fixes-5.2' of git://people.freedesktop.org/~thomash/linux into drm-fixes

A couple of fixes for vmwgfx. Two fixes for a DMA sg-list debug warning
message. These are not cc'd stable since there is no evidence of actual
breakage.
On fix for the high-bandwidth backdoor port which is cc'd stable due to
upcoming hardware, on which the code would otherwise break.
