From e588fa18c1cc490fa75c0b4bd1d4f7758ccd33cf Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Fri, 23 Oct 2015 13:01:50 +0300 Subject: [PATCH] drm/i915: Make intel_dp_source_supports_hbr2() take an intel_dp pointer The function name implies it should get intel_dp, and it mostly used where there is an intel_dp in the context.
