Looks great, thank you.

In strace, string literals tend to be wrapped to be under 80 columns
as well:

	printf("ioctl(-1, IPMICTL_SET_MAINTENANCE_MODE_CMD"
	       " or LIRC_SET_REC_CARRIER_RANGE, [40000]) = %s\n",
	       errstr);

	printf("ioctl(-1, LIRC_GET_FEATURES, [LIRC_CAN_SEND_PULSE"
	       "|LIRC_CAN_SET_SEND_DUTY_CYCLE|LIRC_CAN_USE_WIDEBAND_RECEIVER"
	       "|LIRC_CAN_GET_REC_RESOLUTION|0x8000000]) = %s\n",
	       errstr);

It is usually formatted as follows in strace:

	do_ioctl(LIRC_GET_FEATURES, (unsigned int *) 0x40000);

Since these are just minor formatting nits,
