usb: musb: constify musb_hdrc_config structures
Declare musb_hdrc_config structures as const as they are only stored in the config field of a musb_hdrc_platform_data structure. This field is of type const, so musb_hdrc_config structures having this property can be made const too. Done using Coccinelle: @r disable optional_qualifier@ identifier x; position p; @@ static struct musb_hdrc_config x@p={...}; @ok@ struct musb_hdrc_platform_data pdata; identifier r.x; position p; @@ pdata.config=&x@p; @bad@ position p != {r.p,ok.p}; identifier r.x; @@ x@p @depends on !bad disable optional_qualifier@ identifier r.x; @@ +const struct musb_hdrc_config x; File size before: text data bss dec hex filename 1212 338 0 1550 60e drivers/usb/musb/jz4740.o File size after: text data bss dec hex filename 1268 290 0 1558 616 drivers/usb/musb/jz4740.o File size before: text data bss dec hex filename 6151 333 16 6500 1964 drivers/usb/musb/sunxi.o File size after: text data bss dec hex filename 6215 269 16 6500 1964 drivers/usb/musb/sunxi.o File size before: text data bss dec hex filename 3668 864 0 4532 11b4 drivers/usb/musb/ux500.o File size after: text data bss dec hex filename 3724 808 0 4532 11b4 drivers/usb/musb/ux500.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
