istl_flip is a signed bitfield of one bit so it can be -1 or 0.
However in drivers/usb/host/isp1362-hcd.c:1103:
finish_iso_transfers(isp1362_hcd,
&isp1362_hcd->istl_queue[isp1362_hcd->istl_flip]);
So if isp1362_hcd->istl_flip is set, the 2nd argument becomes
&isp1362_hcd->istl_queue[-1], which is invalid.

A bunch of places assumed pointers were 32-bits in size (bit checking and
debug output), but none of these affected runtime functionality.

HCHWCFG_PULLDOWN_DS2 and HCHWCFG_PULLDOWN_DS1 were swapped. Incorrect
operator precedence in isp1362_hc_start() hid part of the problem.
This fixes a problem where Port 1 in Host mode fails to see disconnects.
