Bhumika Goyal 3774e02c74 usb: isp1760: constify usb_gadget_ops structures
Declare usb_gadget_ops structures as const as they are only stored in
the ops field of a usb_gadget structure. This field is of type const, so
usb_gadget_ops structures having this property can be declared const
too.
Done using Coccinelle:

@r1 disable optional_qualifier@
identifier i;
position p;

static struct usb_gadget_ops i@p={...};

@ok1@
identifier r1.i;
position p;
struct isp1760_udc udc;

udc.gadget.ops=&i@p

@bad@
position p!={r1.p,ok1.p};

@depends on !bad disable optional_qualifier@
identifier r1.i;
