Subject: [PATCH] drm/amd/display: hide an unused variable
Date: Wed, 18 Sep 2019 21:53:58 +0200 [thread overview]
Message-ID: <20190918195418.2042610-1-arnd@arndb.de> (raw)
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.")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
