Previously, the driver always used the amount of precision bits of differential input channels to provide the scale to mV. Though, differential and common-mode voltage channels have different amount of precision bits and the correct number of precision bits must be considered to get to a proper mV scale factor for each one. Use channel specific number of precision bits to provide the correct scale value for each channel.

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.
