Separate the OHCI NXP host controller driver from ohci-hcd

This work is part of enabling multi-platform kernels on ARM.

The two of you seem to be the people who make the most use of

need to reconsider how isochronous underruns get handled.

You are right. If the QH's qtd_list isn't empty then we should WARN_ON

Fix race in LED handling introduced by commit 0eafe4de (USB: serial:
mos7840: add support for MCS7810 devices) which reused the port control
urb for manipulating the LED without making sure that the urb is not
already in use. This could lead to the control urb being manipulated
while in flight.
Fix race in mos7840_get_reg which unconditionally manipulated the
control urb (which may already be in use) by adding a control-urb busy
flag.

These patches fix three (related) races in mos7840. Driver's a bit of
mess...

Fix race in device-type detection introduced by commit 0eafe4de (USB:

Hi!
I'm trying to investigate on the Huawei E3131 wwan interface - like the E398,
this device ignores the at^ndisdup command.
I wanted to verify if my device was running a jungo firmware or not, since I
found contraddictory informations on the network.
To this end, I patched the cdc_ncm driver
