ACPI / battery: Fix warning message in acpi_battery_get_state()
capacity_now should be assigned after comparing it to design_capacity. 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)." Fixes: 232de5143790 (ACPI / battery: fix wrong value of capacity_now reported when fully charged) Signed-off-by: Mariusz Ceier <mceier+kernel@gmail.com> Cc: 3.16+ <stable@vger.kernel.org> # 3.16+ [rjw: Subject] Signed-off-by: Rafael J.
