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

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

Module Name:    src
Committed By:   skrll
Date:           Tue Feb 16 21:17:27 UTC 2016

Modified Files:
        src/sys/dev/usb [nick-nhusb]: uhci.c

Log Message:
Make interrupt handling MP safe by not dropping the bus lock while
traversing the active transfer list.  Instead move the complete transfers
from the active list to a complete list while holding the bus lock.

Once the interrupt list has been traversed we can do callbacks on the
complete list.  usbd_transfer_complete can safely drop the bus lock while
traversing this private list.
