The oversampling ratio is shared by all channels, no matter the type (e.g. single ended or differential). Currently two attributes are declared for each type: - in_voltage-voltage_oversampling_ratio in_voltage-voltage_oversampling_ratio_available - in_voltage_oversampling_ratio in_voltage_oversampling_ratio_available Use the "info_mask_shared_by_all" instead of "info_mask_shared_by_type". Initial value reported after probe is '0' which isn't a valid ratio. (it should be at least 1 by default, e.g. no oversampling). Fix it by storing the oversampling index in the array, instead of its value in adc struct. This fixes the initial condition.

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.
