[bug report] drm/amdgpu/virt: implement VI virt operation interfaces

[Dan Carpenter]

Hello Xiangliang Yu,

The patch ab71ac56f6d8: "drm/amdgpu/virt: implement VI virt operation
interfaces" from Jan 12, 2017, leads to the following static checker
warning:

	drivers/gpu/drm/amd/amdgpu/mxgpu_vi.c:310 xgpu_vi_init_golden_registers()
	warn: string literals are always true.

drivers/gpu/drm/amd/amdgpu/mxgpu_vi.c
   294                  break;
   295          case CHIP_TONGA:
   296                  amdgpu_program_register_sequence(adev,

   298                                                   (const u32)ARRAY_SIZE(
   299                                                   xgpu_tonga_mgcg_cgcg_init));
   300                  amdgpu_program_register_sequence(adev,

   306                                                   (const u32)ARRAY_SIZE(
   307                                                   xgpu_tonga_golden_common_all));
   308                  break;
   309          default:
   310                  BUG_ON("Doesn't support chip type.\n");

BUG_ON() takes a condition argument, not a format string.

   311                  break;
   312          }
   313  }
