Subject: [PATCH 04/04] ARM: mach-shmobile: Rely on run-time IRQ handlers
Date: Tue, 28 Dec 2010 08:27:19 +0000 [thread overview]
Message-ID: <20101228082719.11806.65240.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
Remove now unused IRQ demux code. All R-Mobile and
SH-Mobile processors should register IRQ demux
handlers during run-time.
Signed-off-by: Magnus Damm <damm@opensource.se>
