Commit Message

Commit 1f12d63a14d7 ("drm/i915/dp: Write the source OUI for non-eDP
sinks as well") started writing source OUI for non-eDP sinks as well,
increasing the possibilities of hitting read/write failures either due
to the sink behaviour or hotplug or whatever.

Even before that, commit 3fb0501f0c07 ("drm/i915/display/dp: Reduce log
level for SOURCE OUI write failures") already reduced write failures to
info level when source OUI was just for eDP.

Further reduce the log level to just debug. Switch to struct intel_dp
while at it.

Did you mean intel_display here rather than intel_dp?

Aside from that,

Yes, fixed while pushing!
