Alan Stern 24f531371d USB: EHCI: accept very late isochronous URBs 
Since commits 4005ad4390 (EHCI: implement new semantics for
URB_ISO_ASAP) and c75c5ab575 (ALSA: USB: adjust for changed 3.8 USB
API) became widely distributed, people have been experiencing problems
with audio transfers.  The slightest underrun causes complete failure,
requiring the audio stream to be restarted.

It turns out that the current isochronous API doesn't handle underruns
in the best way.  The ALSA developers would much rather have transfers
that are submitted too late be accepted and complete in the normal
fashion, rather than being refused outright.

This patch implements the requested approach.  When an isochronous URB
submission is so late that all its scheduled slots have already
expired, a debugging message will be printed in the log and the URB
will be accepted as usual.  Assuming it was submitted by a completion
handler (which is normally the case), it will complete shortly
thereafter with all the usb_iso_packet_descriptor status fields marked
-EXDEV.

This fixes (for ehci-hcd)

	https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1191603

It should be applied to all kernels that include commit 4005ad4390.
