[PATCH] drm/nouveau/kms: Fix NULL pointer dereference in nouveau_connector_detect_depth
...ts that causes the oops.
On entry to nouveau_connector_detect_lvds, edid is set to NULL.
The call to nouveau_connector_detect sets nv_connector->edid to valid
memory, with status being set to connector_status_connected and the flow
of execution branching to the out label.
The subsequent call to nouveau_connector_set_edid erronously clears
nv_connector->edid, via the local edid pointer which remains set to NULL.
Fix this by setting edid to the value of the just acquired
nv_connector->edid and call nouveau_connector_set_edid in the out label
only if nv_connector->edid and edid point to different memory addr...

[RFC v4 00/20] drm/dp, i915, nouveau: Cleanup nouveau HPD and add DP features from i915
Most of the reason I'm asking for an RFC here is because this
code pulls a lot of code out of i915 and into shared DP helpers.
Anyway-nouveau's HPD related code has been collecting dust for a while.
Other then the occasional runtime PM related and MST related fixes,
we're missing a lot of nice things that have been added to DRM since
this was originally written. Additionally, the code

[RFC v2 00/20] drm/dp, i915, nouveau: Cleanup nouveau HPD and add DP features from i915
To start off: this patch series is less work to review then it looks -
most (but not all) of the nouveau related work has already been reviewed
elsewhere. Most of the reason I'm asking for an RFC here is because this
code pulls a lot of code out of i915 and into shared DP helpers.
