Check scan_type for error ad4030_get_chan_scale(). Currently, this should never fail, but it is good practice to always check for errors in case of future changes. Calling iio_get_current_scan_type() is moved out of the if statement also to avoid potential issues with future changes instead of assuming that the non-differential case does not use extended scan_type.

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.
