Subject: drm/i915: Replace some loop through encoders with intel_pipe_has_type()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6e2cc0963a962aad91184eaabcf67a106e80e815;p=linux-beck.git

drm/i915: Replace some loop through encoders with intel_pipe_has_type()

In the ironlake mode set code, there was two instances of a loop through
encoders to find out if one of them has INTEL_OUTPUT_LVDS type. Simplify
the code by deleting some lines and use intel_pipe_has_type() instead.
