drm/edid: Set YQ bits in the AVI infoframe according to CEA-861-F
CEA-861-F tells us:
"When transmitting any RGB colorimetry, the Source should set the
YQ-field to match the RGB Quantization Range being transmitted
(e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB,
set YQ=1) and the Sink shall ignore the YQ-field."
So let's go ahead and do that. Perhaps there are sinks that don't
ignore the YQ as they should for RGB?
I wasn't able to find similar text in CEA-861-E, so it would seem
to be a fairly "recent" addition.

According to CEA-861 we can do that as long as the Q we send matches

Previously I think I had misread the spec as saying that you can't
send a non-zero Q at all when QS=0. But that's not what the spec

drm/dp: Store drm_device in MST topology manager
struct drm_dp_mst_topology_mgr currently stores a pointer to struct dev.
Changing this to instead hold a pointer to drm_device is more useful as it
gives access to DRM structures. This also makes it consistent with other
DRM structures like drm_crtc, drm_connector etc.

The list_del() inside the error handling in the eviction loop is
overkill. We have to undo the eviction scan to return the drm_mm back to
a recoverable state, so have to iterate over the full list, but we only
want to report the error once and once we have an error we can return

dma-fence: Introduce drm_fence_set_error() helper
The dma_fence.error field (formerly known as dma_fence.status) is an
optional field that may be set by drivers before calling
dma_fence_signal(). The field can be used to indicate that the fence was
completed in err rather than with success, and is visible to other
consumers of the fence and to userspace via sync_file.
This patch renames the field from status to error so that its meaning is
hopefully more clear (and distinct from dma_fence_get_status() which is
a composite between the error state and signal state) and adds a helper
that validates the preconditions of when it is suitable to adjust the
error field.
