From f3e70d2991df5591263f2e9f83e74cc047462240 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 19 May 2017 23:59:34 +1000 Subject: [PATCH] drm/nouveau/disp: rename nvkm_output_dp to nvkm_dp Not all users of nvkm_output_dp have been changed here. The remaining ones belong to code that's disappearing in upcoming commits. This also modifies the debug level of some messages.
