From 6d64d4256cccd3a452ebd8c37a1d41e2d5dab8c6 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 7 Aug 2007 18:51:19 +0900 Subject: [PATCH] sh: intc: Fix sense regs oops for IRL IRQs. IRL doesn't always define sense registers, so don't bother trying to iterate through the table. This ended up causing an oops on SH-X3 when using IRL mode.
