Alexandru Ardelean 24e1eb5c0d iio: imu: adis16480: make sure provided frequency is positive
It could happen that either `val` or `val2` [provided from userspace] is
negative. In that case the computed frequency could get a weird value.

Fix this by checking that neither of the 2 variables is negative, and check
that the computed result is not-zero.

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.
