Subject: [PATCH] usb: gadget: udc: constify usb_ep_ops structures
Date: Mon, 23 Jan 2017 22:56:04 +0530	[thread overview]
Message-ID: <1485192364-2840-1-git-send-email-bhumirks@gmail.com> (raw)

Declare usb_ep_ops structures as const as they are only stored in the
ops field of an usb_ep structure. This field is of type const, so
usb_ep_ops structures having this property can be made const too.
