Subject: linux-next: manual merge of the usb tree with the usb.current tree

Hi Greg,

Today's linux-next merge of the usb tree got a conflict in
drivers/usb/host/xhci-ring.c between commit 48df4a6fd8c4 ("xhci: Handle
zero-length isochronous packets") from the usb.current tree and commit
29cc88979a88 ("USB: use usb_endpoint_maxp() instead of le16_to_cpu()")
from the usb tree.

I fixed it up (see below) and can carry the fix as necessary.
