With a degraded battery, full_charge_capacity can be less than design_capacity, however it's not sure that capacity_now's max will follow. Example from an affected machine: /sys/class/power_supply/BAT0/charge_full -> 4290000 /sys/class/power_supply/BAT0/charge_full_design -> 5900000 /sys/class/power_supply/BAT0/charge_now -> 5900000 /sys/class/power_supply/BAT0/capacity -> 137 The battery is a degraded one with a full charge, and charge_now is the value of charge_full_design instead of charge_full. Added a new quirk to test and correct this, and a new function to check if the battery is a degraded one or not. This keeps the possibility to be over 100 if it's really the case.

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.
