[PATCH 3/3] powerpc: fix comment in kernel/irq.c
From: Johannes Berg <johannes@sipsolutions.net>
Date: 2006-12-13 13:01:28
kernel/irq.c contains a comment that speaks of -1 and -2 as interrupt numbers, but this is actually dependent on configuration options now. Replace by NO_IRQ and NO_IRQ_ENABLED. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org>
