Functions working with attribute_groups provided by <linux/sysfs.h>
work with const attribute_group. These attribute_group structures do not
change at runtime so mark them as const.
File size before:
text data bss dec hex filename
8657 3496 64 12217 2fb9 drivers/leds/leds-blinkm.o
File size after:
text data bss dec hex filename
8753 3400 64 12217 2fb9 drivers/leds/leds-blinkm.o
This change was made with the help of Coccinelle.

Hi Amitoj,
Similar patch is already queued in the for-next branch
of linux-leds.git.
Thanks,
