Subject: [PATCH 1/2] ib_ipath: Fix probe failure path
Date: Sat, 12 Jun 2010 03:25:09 +0100 [thread overview]
Message-ID: <1276309509.14011.173.camel@localhost> (raw)
[-- Attachment #1: Type: text/plain, Size: 1826 bytes --]
The failure path in ipath_init_one() does not match the cleanup code
in ipath_remove_one() and appears to leave interrupts enabled in some
cases. Change it to match.
Signed-off-by: Ben Hutchings <ben-/+tVBieCtBitmTQ+vhA3Yw@public.gmane.org>

In recent Debian kernel packages this driver is patched to use an
external firmware image for the SD7220. A user reported in
<http://bugs.debian.org/579393> that if the firmware image is missing
the driver crashes about a second later, and I believe this is due to
incomplete cleanup on the failure path. He has not yet had an
opportunity to test this patch.
Ben.
