when we wake up a discharged battery using the "precharge current", it briefly requests requests (0 vols, 0 amps) - presumably while its controller is trying to figure out what's going on... we respect this and stop charging, but that's probably a really bad idea since the battery has had very little chance to accept enough charge to self-power its controller. enabling "REQUESTS_NIL_WHEN_DEAD" gets around that. BUG=b:79354967 BRANCH=none TEST=instrumented code to verify we override the 0 amps request when battery is at 0% charge Change-Id: I1e15e5106ae5cdda94bd1bfd02132b300c9c4665 Signed-off-by: Caveh Jalali <caveh@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/1067010 Commit-Ready: Caveh Jalali <caveh@google.com> Tested-by: Caveh Jalali <caveh@google.com> Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org>
