kernel/irq/proc.c: unprotected iteration over the IRQ action list in name_unique()

setup_irq() releases a desc->lock before calling register_handler_proc(), so
the iteration over the IRQ action list is not protected.

(akpm: the check itself is still racy, but at least it probably won't oops
now).
