Subject: [PATCH 4.19 028/110] opp: ti-opp-supply: Correct the supply in _get_optimal_vdd_voltage call

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

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

From: Keerthy <j-keerthy@...com>

commit 622fecbccfe86a8052dea6b512d3821dcce29994 upstream.

_get_optimal_vdd_voltage call provides new_supply_vbb->u_volt
as the reference voltage while it should be really new_supply_vdd->u_volt.

Cc: 4.16+ <stable@...r.kernel.org> # v4.16+
