Subject: [PATCH 7/7] usbnet: don't initialize transfer buffer before submit status URB
Date: Tue, 12 Jun 2012 09:19:45 +0800 [thread overview]
Message-ID: <1339463985-9006-8-git-send-email-tom.leiming@gmail.com> (raw)
In-Reply-To: <1339463985-9006-1-git-send-email-tom.leiming-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
The line below in intr_complete isn't needed,
memset(urb->transfer_buffer, 0, urb->transfer_buffer_length);
so just remove it.
