commita9d3a9cedcupstream. The Advantech PCI-1713 has 32 analog input channels, but an incorrect bit-mask in the definition of the `PCI171X_MUX_CHANH(x)` and PCI171X_MUX_CHANL(x)` macros is causing channels 16 to 31 to be aliases of channels 0 to 15. Change the bit-mask value from 0xf to 0xff to fix it. Note that the channel numbers will have been range checked already, so the bit-mask isn't really needed.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
