This patch fixes a problem with map_dispc_register_isr() where it
fails to return -EBUSY if it has no more space for registrations.

Looks correct, but a couple of things:
- Missing signed-off
- Indentation is wrong
- Don't use { } when there's just one line in the if block

Please fix those, or alternatively I can fix the bug myself and add you
as reported-by.

 Tomi
