Subject: [PATCH] input: constify attribute_group structures.
Date: Wed, 5 Jul 2017 15:45:25 +0530 [thread overview]
Message-ID: <aa330ec69c70699ed3ed0b84f93c4b62518732dc.1499249046.git.arvind.yadav.cs@gmail.com> (raw)
attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.
File size before:
text data bss dec hex filename
17755 1312 16 19083 4a8b drivers/input/input.o
File size After adding 'const':
text data bss dec hex filename
17947 1120 16 19083 4a8b drivers/input/input.o
