The patch titled
usb gadget: update pxa2xx_udc.c driver to fully support IXP4xx platform
has been removed from the -mm tree. Its filename is
usb-gadget-update-pxa2xx_udcc-driver-to-fully-support.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.

Subject: usb gadget: update pxa2xx_udc.c driver to fully support IXP4xx platform
From: Milan Svoboda <msvoboda@xxxxxxxxxxxxxxx>
This patch adds IXP465 into the list of known devices and adds IXP465 to the
list of devices that have cfr. This is not described in the hardware
documentation, but without it driver don't work.
Workaround (#if 1) that seemed to get rid of lost status irqs is disabled for
IXP4XX as it caused freezes during testing of control messages. No lost irqs
are visible on IXP4XX.
Driver survived tests running over night without any visible problems.
