From: Arnd Bergmann <arnd@xxxxxxxx> The debugfs file is defined unconditionally, but the registration is hidden in an #ifdef, which causes a warning: drivers/gpu/drm/amd/amdgpu/amdgpu_rap.c:110:37: error: unused variable 'amdgpu_rap_debugfs_ops' [-Werror,-Wunused-const-variable] static const struct file_operations amdgpu_rap_debugfs_ops = { ^ in amdgpu_pm.c, the same thing happens with the clocks[] variable: drivers/gpu/drm/amd/pm/amdgpu_pm.c:38:34: error: unused variable 'clocks' [-Werror,-Wunused-const-variable] static const struct cg_flag_name clocks[] = { ^ Since debugfs_create_file() does nothing when debugfs is disabled, removing the ifdefs makes the code more readable and also avoids both warnings.
