Subject: mailbox: constify mbox_chan_ops structures
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8ce33c6ff375b59bfa0a347782c49da94e64bb85;p=linux.git
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;
