Subject: [PATCH 3.13.y-ckt 035/143] power: bq24190: Fix ignored supplicants

3.13.11-ckt18 -stable review patch.  If anyone has any objections, please let me know.

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

From: Krzysztof Kozlowski <k.kozlowski@...sung.com>

commit 478913fdbdfd4a781d91c993eb86838620fe7421 upstream.

The driver mismatched 'num_supplicants' with 'num_supplies' of
power_supply structure.

It provided list of supplicants (power_supply.supplied_to) but did
not set the number of supplicants. Instead it set the num_supplies which
is used when iterating over number of supplies (power_supply.supplied_from).

As a result the list of supplicants was ignored by core because its size
was 0.
