Since commit9bcf15f75c("iio: adc: axp288: Fix TS-pin handling") we preserve the bias current set by the firmware at boot. This fixes issues we were seeing on various models, but it seems our old hardcoded 80ųA bias current was working around a firmware bug on at least one model laptop. In order to both have our cake and eat it, this commit adds a dmi based list of models where we need to override the firmware set bias current and adds the one model we now know needs this to it: The Lenovo Ideapad 100S (11 inch version).

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.
