[patch 1/1] OSS msnd_pinnacle missing return check for request_region()

[Laurent Wandrebeck <l.wandrebeck@free.fr>]

Hi,
in sound/oss/msnd_pinnacle.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.
PS: trying with a MUA this time, since the webmail I used for previous patch 
( [patch 1/1] OSS ali5455 missing return check for request_region() ) wrapped lines :(
