From: Keith Packard Date: Tue, 26 Jul 2011 03:01:56 +0000 (-0700) Subject: drm/i915: In intel_dp_init, replace read of DPCD with intel_dp_get_dpcd X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59f3e272d788305e16098f0b18309919c9216d67;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: In intel_dp_init, replace read of DPCD with intel_dp_get_dpcd Eliminates an open-coded read and also gains the retry behaviour of intel_dp_get_dpcd, which seems like a good idea.
