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}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct usb_gadget_ops i; File size before: drivers/usb/isp1760/isp1760-udc.o text data bss dec hex filename 12434 4136 16 16586 40ca usb/isp1760/isp1760-udc.o File size after: drivers/usb/isp1760/isp1760-udc.o text data bss dec hex filename 12530 4048 16 16594 40d2 usb/isp1760/isp1760-udc.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
