Since commit e8f4818895b3 ("[media] lirc: advertise LIRC_CAN_GET_REC_RESOLUTION and improve") lircd uses the ioctl LIRC_GET_REC_RESOLUTION to determine the shortest pulse or space that the hardware can detect. This breaks decoding in lirc because lircd expects the answer in microseconds, but nanoseconds is returned.
