        src/sys/dev/usb: ohci.c

Log Message:
Fix a done list handling bug which exhibits under high shared interrupt
rate and bus traffic.  As the interrupt register is read after checking
hcca_done_head, there was a small chance of dropping a done list.
Ignore OHCI_WDH interrupt bit if hcca_done_head is zero so that OHCI_WDH
is processed later.
