History of the function:96788d2aa4assume system is running on AC power when no battery found795e86b4f1ignore USB-C ports in power source mode when detecting system is running on AC powerc19a51bec4invert ac_power() source type check6d89003462assume ac when /sys/class/power_supply is missing240dbaa44fadd ConditionACPower= Interestingly, the return condition 'on_ac_power == found_online || !found_offline' was there from the very beginning, and even Yu's latest change doesn't change this, but only extends it to 'on_ac_power == found_online || !found_offline || !found_battery'. This means that any system with no AC power supply will be unconditionally classified as on_ac_power. Let's change the logic: if we have an online AC supply, answer is "yes". If no supplies, but we have a battery, answer is "no". Otherwise, assume "yes", based on the assumption that presense of a battery would at least be always reported, even if an AC power supply might not be. Fixes #24407. It also shouldn't impact previous fixes: assume ac when /sys/class/power_supply is missing, ignore USB-C ports in power source mode, assume system is running on AC power when no battery found.
