USB: UHCI: accept very late isochronous URBs
Commit 24f531371de1 (USB: EHCI: accept very late isochronous URBs)
changed the isochronous API provided by ehci-hcd. URBs submitted too
late, so that the time slots for all their packets have already
expired, are no longer rejected outright. Instead the submission is
accepted, and the URB completes normally with a -EXDEV error for each
packet. This is what client drivers expect.
This patch implements the same policy in uhci-hcd. It should be
applied to all kernels containing commit c44b225077bb (UHCI: implement
new semantics for URB_ISO_ASAP).
