This resolution breaks the build.

  drivers/gpu/drm/xe/xe_device_sysfs.c: In function 'xe_device_sysfs_init':
  drivers/gpu/drm/xe/xe_device_sysfs.c:300:25: error: label 'cleanup' used but not defined
    300 |                         goto cleanup;
        |                         ^~~~

I think those should just be 'return ret', as it appears that
fb3c27a69c473 already includes ff89a4d285c82, so I think you can just
take the right side of the conflict wholesale.

Cheers,
Nathan
