[00/30,Set,4] Rid W=1 warnings from GPU

Message

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

Exciting times (using Arm as the benchmark):

 Before these sets:
  5031 drivers/gpu/
   3923 drivers/gpu/drm/amd/
    258 drivers/gpu/drm/radeon/
     95 drivers/gpu/drm/nouveau/
     77 drivers/gpu/drm/msm/

 After these sets:
  2236 drivers/gpu/
    1949 drivers/gpu/drm/amd/
      97 drivers/gpu/drm/nouveau/
      83 drivers/gpu/drm/msm/
      40 drivers/gpu/drm/radeon

Couple more to go.

Plan is to finsish off Radeon, then start targeting AMD tomorrow.
