Hi all,

After merging the drm-msm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/msm/msm_drv.c:59:1: error: data definition has no type or storage class [-Werror]
   59 | DECLARE_FAULT_ATTR(fail_gem_alloc);
      | ^~~~~~~~~~~~~~~~~~
drivers/gpu/drm/msm/msm_drv.c:59:1: error: type defaults to 'int' in declaration of 'DECLARE_FAULT_ATTR' [-Werror=implicit-int]
drivers/gpu/drm/msm/msm_drv.c:59:1: error: parameter names (without types) in function declaration [-Werror]
drivers/gpu/drm/msm/msm_drv.c:60:1: error: data definition has no type or storage class [-Werror]
   60 | DECLARE_FAULT_ATTR(fail_gem_iova);
      | ^~~~~~~~~~~~~~~~~~

  454 |         if (should_fail(&fail_gem_alloc, args->size))
      |             ^~~~~~~~~~~
cc1: all warnings being treated as errors

Presumably caused by commit

  506efcba3129 ("drm/msm: carve out KMS code from msm_drv.c")

I have used the drm-msm tree from next-20231009 for today.
