Acer aspire A7 with Gentoo got battery support #26

The module runs on A715-42G-R8T3. In order to don't lose it on kernel updates I prepared an ebuild to include the module in a Gentoo environment. I compiled it with gcc-12.2.1.

With health mode activated battery level charges up to 79%. I encountered a weird behaviour: In case AC is plugged with level >80% it stays at that level (acpi returns 89% since hours).

I ran the calibration and it worked as expected: full-charge -> ~empty -> full recharge.

Thank you for the feedback! I see the same behaviour if the battery is charged above over 80% and the AC is plugged in. I suppose this is intentional. In particular, it is not caused by this module, i.e. I would expect that you would see the same behaviour with the Acer's own Windows tool.
