Commit Message

Arnd Bergmann Jan. 3, 2021, 2:02 p.m. UTC 
From: Arnd Bergmann <arnd@arndb.de>


Some of the newly added code is hidden inside of #ifdef
blocks, but one variable is unused when debugfs is disabled:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8370:8: error: unused variable 'configure_crc' [-Werror,-Wunused-variable]

Change the #ifdef to an if(IS_ENABLED()) check to fix the warning
and avoid adding more #ifdefs.

Fixes: c920888c604d ("drm/amd/display: Expose new CRC window property")
