Date: Thu, 01 Jul 2010 10:33:41 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Dinh Nguyen <Dinh.Nguyen@...escale.com> Subject: [patch 035/164] USB: mxc: gadget: Fix bitfield for calculating maximum packet size 2.6.33-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dinh Nguyen <Dinh.Nguyen@...escale.com> commit 88e3b59b5adce5b12e205af0e34d518ba0dcdc0c upstream. The max packet length bit mask used for isochronous endpoints should be 0x7FF instead of 0x8FF. 0x8FF will actually clear higher-order bits in the max packet length field. This patch applies to 2.6.34-rc6.
