From 565f26a39d8e49745fda00d2303138aea831fd29 Mon Sep 17 00:00:00 2001 From: Harry Wentland Date: Mon, 16 Oct 2017 20:10:00 -0400 Subject: [PATCH] drm/amd/display: Small comment on dc_commit_planes_to_stream Having one struct on the stack was somewhat confusing. Also mention that the whole function should eventually go.
