Without CONFIG_DEBUG_FS, we get a warning for an unused variable:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:6020:33: error: unused variable 'source' [-Werror,-Wunused-variable]
Hide the variable in an #ifdef like its only users.
Fixes: 14b2584636c6 ("drm/amd/display: add functionality to grab DPRX CRC entries.") Reviewed-by: Harry Wentland harry.wentland@amd.com Signed-off-by: Arnd Bergmann arnd@arndb.de --- This was a bugfix for a commit that landed in v5.4-rc1. The fix was applied by Alex Deucher on Sep 19, but is still not seen in linux-next. Resending to make sure this makes it into v5.4-final, but please ignore if this is already coming. --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 2 ++ 1 file changed, 2 insertions(+)
