mailbox: constify mbox_chan_ops structures
Check for mbox_chan_ops structures that are only stored in the ops field of a mbox_controller structure. This field is of type const struct mbox_chan_ops *, so mbox_chan_ops structures having this property can be declared as const. Done using Coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ struct mbox_chan_ops i@p = {...}; @ok1@ identifier r1.i; struct hi6220_mbox mbox; struct slimpro_mbox ctx; position p; @@ ( mbox.controller.ops=&i@p | ctx.mb_ctrl.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 mbox_chan_ops i; File size details: text data bss dec hex filename 2310 248 0 2558 9fe drivers/mailbox/hi6220-mailbox.o 2366 192 0 2558 9fe drivers/mailbox/hi6220-mailbox.o 1500 248 0 1748 6d4 mailbox/mailbox-xgene-slimpro.o 1556 192 0 1748 6d4 mailbox/mailbox-xgene-slimpro.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
