I have mentioned all this in commit message. I have added below
message in patch. Please check my patch.

"attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const."

Even checkpatch.pl will through warning.
