I have these patches from last October when we've looked at what
causes problems with mac99 and USB. We've found the main problem is
likely not allowing pending packets per endpoint which we did not fix
but these patches came out of debugging that and trying to improve the
device model so eventually the real problem could be fixed more
easily. So these are just clean ups and fixing one potential issue
with isochronous transfers breaking pending async packet but it does
not solve all problems OHCI currently has. I'm sending it anyway as I
don't plan to work further on this so this series could be taken as is
for now.
Regards,
BALATON Zoltan (5):
usb/ohci: Move trace point and log ep number to help debugging
usb/ohci: Move cancelling async packet to ohci_stop_endpoints()
usb/ohci: Move USBPortOps related functions together
usb/ohci: Merge ohci_async_cancel_device() into ohci_child_detach()
usb/ohci: Don't use packet from OHCIState for isochronous transfers
