Christian Lamparter 6982869d99 p54usb: utilize usb_reset_device for 3887
Sometimes on unload or reboot the 3887 USB devices become stuck.
<usual log entry>
kernel: usbcore: registered new interface driver p54usb
kernel: usb 2-10: (p54usb) reset failed! (-110)
kernel: p54usb: probe of 2-10:1.0 failed with error -110
[...]

and a physical unplug and replug was necessary.
However we should be able to do this in software as well,
without any user interaction.

Christian Lamparter dd397dc9dd p54usb: rewriting rx/tx routines to make use of usb_anchor's facilities
Alan Stern found several flaws in p54usb's implementation and annotated:
"usb_kill_urb() and similar routines do not expect an URB's completion
routine to deallocate it.  This is almost obvious -- if the URB is deallocated
before the completion routine returns then there's no way for usb_kill_urb
to detect when the URB actually is complete."

This patch addresses all known limitations in the old implementation and fixes
khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

Christian Lamparter 32ddf07185 p54: rename prism54xyz -> p54xyz
It's been a long time, but fullmac prism54 driver is still around...
I think we should rename every prism54* in order to avoid some
confusion about "what is actually what" in the future ;-).
