The only place sdw_slave_dev_attr_group is used is when its address is passed to devm_device_add_group() which takes a pointer to const struct attribute_group. Make it const to allow the compiler to put it in read-only memory. This makes all attribute_group structs in the file const. Done with the help of Coccinelle.
