From cc7e422d3db338bf00ac73b4575668d149a25a34 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Mon, 4 Feb 2019 09:32:07 -0500 Subject: [PATCH] drm/amd/display: Don't re-enable CRC when CONFIG_DEBUG_FS isn't defined [Why] When CONFIG_DEBUG_FS isn't defined then amdgpu_dm_crtc_set_crc_source is NULL. This causes a compilation error since it's being called unconditionally. [How] Guard the call based on CONFIG_DEBUG_FS - CRC capture isn't supported without this.
