From d8199c85f3e447717cfc530ce114f7c8fbc0982c Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 22 Oct 2020 16:16:54 +0300 Subject: [PATCH] drm/msm/dpu: simplify interface flush handling Instead of calling 4 callbacks to set pending masks, call just one to update both pending_flush_mask and pending_intf_flush mask. Note, that CMD mode support incorrectly did not update pending_intf_flush mask, breaking CMD support on SC7180/SM8x50.
