The ti-ads1015 driver has eight iio voltage channels and each iio channel can hold own scale information. The ADS1015 device only have a single config register which contains an input multiplexer selection, PGA and data rate settings. So the driver should load the correct settings when the input multiplexer selection is changed. However, regardless of which channlel is currently selected, changing any iio channel's scale information immediately overwrites the current PGA setting in the config register. It is harmless because the correct PGA settings are reloaded just before getting adc result anyway. But it is unnecessary register update and should be removed.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
