I applied your patch, but sadly it didn't fix my issue. I agree that 
your approach (actually returning drmmode_set_cursor() errors instead of 
relying on a side-effect) is better though. But it appears that I would 
need drmmode_show_cursor()'s errors to be reported for the same approach 
to work in my case.

I see that the load_cursor_argb_check() hook has been added apparently 
to palliate the fact that load_cursor_argb() does not return an error 
status, would it be acceptable to apply the same principle to show_cursor()?

Thanks,
Alex.
