[ Upstream commitb73f08bb7f] When reading in_voltage_scale we can get something like: root@analog:/sys/bus/iio/devices/iio:device2# cat in_voltage_scale 0.038146 However, when reading the available options: root@analog:/sys/bus/iio/devices/iio:device2# cat in_voltage_scale_available 2000.000000 2100.000006 2200.000007 2300.000008 2400.000009 2500.000010 which does not make sense. Moreover, when trying to set a new scale we get an error because there's no call to __ad9467_get_scale() to give us values as given when reading in_voltage_scale. Fix it by computing the available scales during probe and properly pass the list when .read_available() is called. While at it, change to use .read_available() from iio_info. Also note that to properly fix this, adi-axi-adc.c has to be changed accordingly.

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 Restructured Text 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.
