Subject: drm/nouveau: remove special-casing of hotplug detection type
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1cb70b30e4c6f25cf69ec0ab33db0218490f928d;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

drm/nouveau: remove special-casing of hotplug detection type

If we support PGPIO interrupts, and know a hotplug GPIO tag for a
connector we use HPD, otherwise POLL_CONNECT.
