Subject: Input: ads7846 - constify attribute_group structures
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9e938deceaea1496af4dda420e8f854691d4321f;p=linux.git
Input: ads7846 - constify attribute_group structures
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
9086 624 0 9710 25ee drivers/input/touchscreen/ads7846.o
File size After adding 'const':
text data bss dec hex filename
9198 496 0 9694 25de drivers/input/touchscreen/ads7846.o
