USB: serial: ftdi_sio: only allow valid event_char values The "event_char" device attribute value, when written, is interpreted as an enable bit in bit 8, and an "event character" in bits 7 to 0. Return an error -EINVAL for out-of-range values. Use kstrtouint() to parse the integer instead of the obsolete simple_strtoul().
