Subject[PATCH 3/3] mfd: pcf50633: Constify static struct attribute_group
Date
The only usage of pcf_attr_group is to pass its address to
sysfs_create_group() and sysfs_remove_group(), both which takes pointers
to const attribute_group structs. Make it const to allow the compiler to
put it in read-only memory.

Done with the help of coccinelle.
