Pull USB merge for 3.4-rc1 from Greg KH:
"Here's the big USB merge for the 3.4-rc1 merge window.
Lots of gadget driver reworks here, driver updates, xhci changes, some
new drivers added, usb-serial core reworking to fix some bugs, and
other various minor things.
There are some patches touching arch code, but they have all been
acked by the various arch maintainers."

When applying commit 7d26b58 (fix failure path in
dwc3_pci_probe()), I mistakenly left out one of the
possible failures where we would return success even
on the error case.
This patch fixes that mistake.

dwc3_pci_probe() would return success even if the calls to
dwc3_get_device_id() or platform_device_alloc() fail, fix that.

This patch enables to use devm_xxx functions during probing driver.
The devm_xxx series functions are able to release resource when the
driver is detatched. We can remove several codes to release resources
in the probe function.

Glue needs to be freed on exiting the function in an error case.
Furthermore, pci, which is the first argument to the probe function should
not be freed before leaveing the function, as it is reused at the call
site. So the free of pci is changed to free glue instead.
A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)
// <smpl>
@r exists@

if we want to support situations where we have
both SoC and PCIe versions of the IP on the same
platform, we need to have sequential numbers between
them, otherwise we will still have name collisions.
Because of that, we need to move dwc3_get/put_device_id()
to core.c and export that symbol to be used by glue
layers.

There's no need to add driver_data for something
we can fetch from HW.
This also makes our id_table unnecessary - at least
for now -, so we also remove it on the same patch.

Some people think that this line is not compatible with the GPL. The
statement was required due to the Buenos Aires Convention and is now
deprecated. I remove it because it is said that it is pointless nowdays.

The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.
Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.
The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.
More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.
While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.
