From ee34801cc0e8f07ad210c220986e77dd46dd0b3e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 15 Jan 2020 21:08:11 +0200 Subject: [PATCH] drm/i915: Prefer to use the pipe to index the ddb entries MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Let's use the pipe rather than the silly 'i' iterator from for_each_oldnew_intel_crtc_in_state() for indexing the ddb entries array. Maybe one day we can assume c99 and hide the 'i' entirely from sight.
