The bd79124 has ADC inputs which can be muxed to be GPIOs. The driver
supports this by registering a GPIO-chip for channels which aren't used
as ADC.
The Kconfig entry does not handle the dependency to GPIOLIB, which
causes errors:
ERROR: modpost: "devm_gpiochip_add_data_with_key" [drivers/iio/adc/rohm-bd79124.ko] undefined!
ERROR: modpost: "gpiochip_get_data" [drivers/iio/adc/rohm-bd79124.ko] undefined!
at linking phase if GPIOLIB is not configured to be used.
Fix this by adding dependency to the GPIOLIB.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
