[PATCH v2 0/2] hw: usb: hcd-ohci: fix oob access and loop issues

[P J P]

From: Prasad J Pandit <pjp@fedoraproject.org>

Hello,

* While servicing transfer descriptors(TD) in ohci_service[_iso]_td
  routines, it may lead to out-of-bounds access and/or infinite loop
  issues, as the OHCI controller driver may supply malicious values
  to derive frame_number, start_addr, end_addr etc. variables.

* This series breaks earlier single patch into two.
  One for an out-of-bounds access issue and another to fix infinite
  loop case.

Thank you.
