Subject: [PATCH] power: add const to bin_attribute structures
Date: Wed, 2 Aug 2017 15:59:38 +0530 [thread overview]
Message-ID: <1501669778-25033-1-git-send-email-bhumirks@gmail.com> (raw)
Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file or
device_{remove/create}_bin_file. The corresponding parameters
passed are of type const, so declare the structures to be const.
Done using Coccinelle:
@m disable optional_qualifier@
identifier s;
position p;
@@
static struct bin_attribute s@p={...};
@okay1@
position p;
identifier m.s;
@@
(
sysfs_create_bin_file(...,&s@p,...)
|
sysfs_remove_bin_file(...,&s@p,...)
)
@bad@
position p!={m.p,okay1.p};
identifier m.s;
@@
s@p
@change depends on !bad disable optional_qualifier@
identifier m.s;
@@
static
+const
struct bin_attribute s={...};
Same script was modified for device_{create/remove}_bin_file functions.
