[PATCH] hidpp: try harder not to report 0% battery

[Martin Pitt]

Hey Peter Wu,

Peter Wu [2013-09-03 23:24 +0200]:
>  (1) If the K800 keyboard is charging via the USB cable, it will report

>  (2) When the K800 has fully charged (but with the cable still plugged

Two words: hardware sucks :-)

Thanks for this polishing! Applied.
