Subject: [patch 1/1] OSS gus_wave missing return check for request_region()
Date: Fri, 17 Mar 2006 12:13:35 +0100 [thread overview]
Message-ID: <200603171213.35891.l.wandrebeck@free.fr> (raw)
Hi,
in sound/oss/gus_wave.c, request_region() is called without checking the return
value. Here is a simple patch to fix it.
Patch against 2.6.16-rc6-git8.
Please CC me on replies.
Regards.
