CVS commit: [nick-nhusb] src/sys/dev/usb

["Nick Hudson" <skrll%netbsd.org@localhost>]

Module Name:    src
Committed By:   skrll
Date:           Sun Jan 10 10:16:00 UTC 2016

Modified Files:
        src/sys/dev/usb [nick-nhusb]: ohci.c ohcivar.h

Log Message:
Do the same loan dance with control transfers as with other transfer
types.  That is,

        Use the pipe "tail" TD as our first and loan our first TD to the
        next transfer.

Sprinkle the above comment where necessary.

Also, remove a TD from the hash list BEFORE calling into
usb_transfer_complete.  It might get reused when starting the next
transfer.
