The current EINVAL value is more applicable to embedded library, where user can actually put the fixed value to the sensor. In case of the driver if the value of the channel is invalid it is better in inform userspace that Channel was out of range as that implies more to internal driver error than invalid input. It also makes for easier debugging of where the error comes from during the development.

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.
