I see 2 options here: * let 'name' be a 'const char *', and do a typecast. This works as long as led_trigger_rename is called only on led_triggers with non-const 'name' storage. * put the storage of trigger name inside struct led_trigger conditionally (like can_dev does with their echo_skb), and when calling led_trigger_rename(), test if 'name' points to that storage. Maybe there are other possibilities. The latter is the safe way to do, but takes a bit more code. The first way is a quick one ...
