X-Git-Tag: v6.12-rc1~160^2~2

power: supply: ab8500: Constify struct kobj_type

This 'struct kobj_type' is not modified. It is only used in
kobject_init_and_add() which takes a 'const struct kobj_type *ktype'
parameter.

Constifying this structure and moving it to a read-only section,
and can increase over all security.
