[SRU] [Bionic] [PATCH 0/5] Gracefully handle ACPI battery status on Asus laptops

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1745032

[Impact]
My original fix for LP: #1745032 got placed by a more general solution,
so replace the old one with the new one.

1) The DMI based solution got reverted, so we won't be able to SRU any
new affected models from upstream.
2) Many Asus laptops are affected by this bug, DMI quirk table will be really
unmaintainable.

[Test]
Along with fixes in UPower, Gnome Settings Daemon and Gnome Shell, the
user confirm the kernel fix works.

[Fix]
Reports the power status as POWER_SUPPLY_STATUS_NOT_CHARGING, the
userspace will handle the rest.

[Regression Potential]
Low. It covers a corner case when "power_supply_is_system_supplied()
&& battery->rate_now == 0", other cases are unaffected.

    discharging state

    it is broken
