-/**
- * gpiotools_request_linehandle() - request gpio lines in a gpiochip
- * @device_name:	The name of gpiochip without prefix "/dev/",
- *			such as "gpiochip0"
- * @lines:		An array desired lines, specified by offset
- *			index for the associated GPIO device.
- * @num_lines:		The number of lines to request.
- * @flag:		The new flag for requsted gpio. Reference
- *			"linux/gpio.h" for the meaning of flag.
- * @data:		Default value will be set to gpio when flag is
- *			GPIOHANDLE_REQUEST_OUTPUT.
- * @consumer_label:	The name of consumer, such as "sysfs",
- *			"powerkey". This is useful for other users to
- *			know who is using.
- *
- * Request gpio lines through the ioctl provided by chardev. User
- * could call gpiotools_set_values() and gpiotools_get_values() to
- * read and write respectively through the returned fd. Call
- * gpiotools_release_linehandle() to release these lines after that.
- *
- * Return:		On success return the fd;
- *			On failure return the errno.
