    Subject[054/115] ds2760_battery: Fix calculation of time_to_empty_now
    2.6.32-longterm review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Sven Neumann <s.neumann@raumfeld.com>

    commit 86af95039b69a90db15294eb1f9c147f1df0a8ea upstream.

    A check against division by zero was modified in commit b0525b48.
    Since this change time_to_empty_now is always reported as zero
    while the battery is discharging and as a negative value while
    the battery is charging. This is because current is negative while
    the battery is discharging.

    Fix the check introduced by commit b0525b48 so that time_to_empty_now
    is reported correctly during discharge and as zero while charging.
