All of the SH clocksource drivers follow the scheme that the IRQ is setup prior to registering the clockevent. The interrupt handler in the clockevent cases looks to the event handler function pointer being filled in by the registration code, permitting us to get in to situations where asserted IRQs step in to the handler before registration has had a chance to complete and hitting a NULL pointer deref. In practice this is not an issue for most platforms, but some of them with fairly special loaders (or that are chain-loading from another kernel) may enter in to this situation. This fixes up the oops reported by Rafael on hp6xx.
