Subject: linux-next: build failure after merge of the amdgpu tree

Hi all,

After merging the amdgpu tree, today's linux-next build (powerpc
allyesconfig) failed like this:

In file included from drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:42:
drivers/gpu/drm/amd/amdgpu/amdgpu.h:1559:13: error: 'amdgpu_choose_low_power_state' defined but not used [-Werror=unused-function]
 1559 | static void amdgpu_choose_low_power_state(struct amdgpu_device *adev) { }
      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

(and many, many more)

Caused by commit

  c77536b15b7a ("drm/amd: Stop evicting resources on APUs in suspend")

I have applied the following patch for today.
