-/**
- * struct lirc_driver - Defines the parameters on a LIRC driver
- *
- * @name:		this string will be used for logs
- *
- * @minor:		indicates minor device (/dev/lirc) number for
- *			registered driver if caller fills it with negative
- *			value, then the first free minor number will be used
- *			(if available).
- *
- * @code_length:	length of the remote control key code expressed in bits.
- *
- * @buffer_size:	Number of FIFO buffers with @chunk_size size. If zero,
- *			creates a buffer with BUFLEN size (16 bytes).
- *
- * @sample_rate:	if zero, the device will wait for an event with a new
- *			code to be parsed. Otherwise, specifies the sample
- *			rate for polling. Value should be between 0
- *			and HZ. If equal to HZ, it would mean one polling per
- *			second.
- *
- * @features:		lirc compatible hardware features, like LIRC_MODE_RAW,
- *			LIRC_CAN_*, as defined at include/media/lirc.h.
- *
- * @chunk_size:		Size of each FIFO buffer.
- *
- * @data:		it may point to any driver data and this pointer will
- *			be passed to all callback functions.
- *
- * @min_timeout:	Minimum timeout for record. Valid only if
- *			LIRC_CAN_SET_REC_TIMEOUT is defined.
- *
- * @max_timeout:	Maximum timeout for record. Valid only if
- *			LIRC_CAN_SET_REC_TIMEOUT is defined.
- *
- * @add_to_buf:		add_to_buf will be called after specified period of the
- *			time or triggered by the external event, this behavior
- *			depends on value of the sample_rate this function will
- *			be called in user context. This routine should return
- *			0 if data was added to the buffer and -ENODATA if none
- *			was available. This should add some number of bits
- *			evenly divisible by code_length to the buffer.
- *
- * @rbuf:		if not NULL, it will be used as a read buffer, you will
- *			have to write to the buffer by other means, like irq's
- *			(see also lirc_serial.c).
- *
- * @set_use_inc:	set_use_inc will be called after device is opened
- *
- * @set_use_dec:	set_use_dec will be called after device is closed
- *
- * @rdev:		Pointed to struct rc_dev associated with the LIRC
- *			device.
- *
- * @fops:		file_operations for drivers which don't fit the current
- *			driver model.
- *			Some ioctl's can be directly handled by lirc_dev if the
- *			driver's ioctl function is NULL or if it returns
- *			-ENOIOCTLCMD (see also lirc_serial.c).
- *
- * @dev:		pointer to the struct device associated with the LIRC
- *			device.
- *
- * @owner:		the module owning this struct
