+Subject: [PATCH 11/12] USB: EHCI: add ignore_oc flag to disable overcurrent
+ checking
+
+This patch adds an ignore_oc flag which can be set by EHCI controller
+not supporting or wanting to disable overcurrent checking. The EHCI
+platform data in include/linux/usb/ehci_pdriver.h is also augmented to
+take advantage of this new flag.
