Subject: [47/65] USB: cdc-wdm: better allocate a buffer that is at least as big as we tell the USB core
Date: Wed, 01 Feb 2012 12:56:27 -0800	[thread overview]
Message-ID: <20120201205741.585485432@clark.kroah.org> (raw)

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

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

From: Bjørn Mork <bjorn@mork.no>

commit 655e247daf52b202a6c2d0f8a06dd2051e756ce4 upstream.

As it turns out, there was a mismatch between the allocated inbuf size
(desc->bMaxPacketSize0, typically something like 64) and the length we
specified in the URB (desc->wMaxCommand, typically something like 2048)
