-Subject: 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.
