Call irq_set_chained_handler_and_data() to clear the chained handler and the handler's data under irq_desc->lock.

Is there any chance that you can apply it? Thanks, Martin
v4: - resend after two months - clean up the commit message while at it v3: - rewrite the commit message again. this is no race condition if we remove the interrupt handler. sorry for the noise. v2: - rewrite the commit message to clarify that this is a bugfix
