[PATCH] amdgpu: fix gcc-4.8 build warnings

Arnd Bergmann arnd at arndb.de
Tue Apr 28 21:54:27 UTC 2020


Older compilers warn about initializers with incorrect curly
braces:

drivers/gpu/drm/drm_dp_mst_topology.c: In function 'drm_dp_mst_dsc_aux_for_port':
drivers/gpu/drm/drm_dp_mst_topology.c:5497:9: error: missing braces around initializer [-Werror=missing-braces]
  struct drm_dp_desc desc = { 0 };
         ^

Change all instances in the amd gpu driver to using the GNU empty
initializer extension.
