Subject: drm/i915: Polish possible_clones setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: c08f995a284dc202a934530ee73cc7136665af38
Patch-mainline: v5.5-rc1
References: bsc#1152489

Replace the hand rolled stuff with drm_encoder_mask() when populating
possible_clones, and rename the function to
intel_encoder_possible_clones() to make it clear what it's used for.
