Subject: [PATCH 3.10 28/53] USB: ipaq.c: fix a timeout loop
Date: Wed, 27 Jan 2016 10:15:47 -0800 [thread overview]
Message-ID: <20160127180650.423894084@linuxfoundation.org> (raw)
In-Reply-To: <20160127180648.932559859@linuxfoundation.org>
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@oracle.com>
commit abdc9a3b4bac97add99e1d77dc6d28623afe682b upstream.
The code expects the loop to end with "retries" set to zero but, because
it is a post-op, it will end set to -1. I have fixed this by moving the
decrement inside the loop.
Fixes: 014aa2a3c32e ('USB: ipaq: minor ipaq_open() cleanup.')
