Subject[PATCH] [media] imon: constify attribute_group structures.
Date
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
18551 2256 77 20884 5194 drivers/media/rc/imon.o

File size After adding 'const':
text data bss dec hex filename
18679 2160 77 20916 51b4 drivers/media/rc/imon.o
