Subject: [PATCH 4/8] drivers: net: usb: Remove unnecessary alloc/OOM messages
Date: Sun,  3 Feb 2013 19:28:11 -0800	[thread overview]
Message-ID: <821617b66116470eb036324879d584fea2bf8a70.1359939013.git.joe@perches.com> (raw)
In-Reply-To: <cover.1359939012.git.joe@perches.com>

alloc failures already get standardized OOM
messages and a dump_stack.
