Subject: [ 21/85] usb: acm: fix the computation of the number of data bits
Date: Thu, 25 Oct 2012 17:05:39 -0700	[thread overview]
Message-ID: <20121026000033.246145177@linuxfoundation.org> (raw)
In-Reply-To: <20121026000031.107227138@linuxfoundation.org>

3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicolas Boullis <nboullis@debian.org>

commit 301a29da6e891e7eb95c843af0ecdbe86d01f723 upstream.

The current code assumes that CSIZE is 0000060, which appears to be
wrong on some arches (such as powerpc).
