[PATCH] acpi/battery: capacity_now should be assigned after comparing it to design_capacity.

From: Mariusz Ceier
Date: Sat Aug 09 2014 - 05:43:32 EST


From: Mariusz Ceier <mceier+kernel@xxxxxxxxx>

Otherwise warning is printed even when capacity_now before assignment is
equal to design_capacity, making the check useless and "current charge level" wrong
(it should be higher than, not equal to, "maximum charge level", which is
full_charge_capacity):

"battery: reported current charge level (56410) is higher than reported
maximum charge level (56410)."
