Jiri Pirko 65c95f7891 dpll: sanitize possible null pointer dereference in dpll_pin_parent_pin_set() 
User may not pass DPLL_A_PIN_STATE attribute in the pin set operation
message. Sanitize that by checking if the attr pointer is not null
and process the passed state attribute value only in that case.
