[Intel-gfx] [PATCH 1/2] drm/dp: Handle zeroed port counts in drm_dp_read_downstream_info()

[Intel-gfx] [PATCH 1/2] drm/dp: Handle zeroed port counts in drm_dp_read_downstream_info()

[Lyude Paul]

While the DP specification isn't entirely clear on if this should be
allowed or not, some branch devices report having downstream ports present
while also reporting a downstream port count of 0. So to avoid breaking
those devices, we need to handle this in drm_dp_read_downstream_info().

So, to do this we assume there's no downstream port info when the
downstream port count is 0.

[Intel-gfx] [PATCH 2/2] drm/dp: Drop open-coded drm_dp_is_branch() in drm_dp_read_downstream_info()

[Lyude Paul]

Noticed this while fixing another issue in drm_dp_read_downstream_info(),
the open coded DP_DOWNSTREAMPORT_PRESENT check here just duplicates what we
already do in drm_dp_is_branch(), so just get rid of it.

BTW that DPCD_REV check looks rather wrong.
