-Subject: [PATCH 1/3] usb: ehci: add spurious flag to disable overcurrent
- checking
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-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.
