bab5417f5f USB: misc: iowarrior: add support for the 100 device 
Add a new device id for the 100 devie.  It has 4 interfaces like the 28
and 28L devices but a larger endpoint so more I/O pins.

5f6f8da2d7 USB: misc: iowarrior: add support for the 28 and 28L devices 
Add new device ids for the 28 and 28L devices.  These have 4 interfaces
instead of 2, but the driver binds the same, so the driver changes are
minimal.

51d22e855e usb: usb3503: Convert to use GPIO descriptors 
This converts the USB3503 to pick GPIO descriptors from the
device tree instead of iteratively picking out GPIO number
references and then referencing these from the global GPIO
numberspace.

The USB3503 is only used from device tree among the in-tree
platforms. If board files would still desire to use it they can
provide machine descriptor tables.

Make sure to preserve semantics such as the reset delay
introduced by Stefan.

3c11c4bed0 USB: adutux: fix interface sanity check 
Make sure to use the current alternate setting when verifying the
interface descriptors to avoid binding to an invalid interface.

Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

91feb01596 appledisplay: fix error handling in the scheduled work 
The work item can operate on

1. stale memory left over from the last transfer
the actual length of the data transfered needs to be checked
2. memory already freed
the error handling in appledisplay_probe() needs
to cancel the work in that case

can stop the URB unconditionally in tower_abort_transfers() and the URB
