This patchset improves support for SBS compliant batteries. Due to
the changes, the battery now exposes 32 power supply properties and
(un)plugging it generates a backtrace containing the following message
without the first patch in this series:
---------------------------
WARNING: CPU: 0 PID: 20 at lib/kobject_uevent.c:659 add_uevent_var+0xd4/0x104
add_uevent_var: too many keys
---------------------------
For references this is what an SBS battery status looks like after
the patch series has been applied:
