Subject: [PATCH 4.6 21/56] regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixed

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

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

From: Axel Lin <axel.lin@...ics.com>

commit 43160ffd12c8d1d331362362eea3c70e04b6f9c4 upstream.

Use regulator_list_voltage_linear_range in rpm_smps_ldo_ops_fixed is
wrong because it is used for fixed regulator without any linear range.
The rpm_smps_ldo_ops_fixed is used for pm8941_lnldo which has fixed_uV
set and n_voltages = 1. In this case, regulator_list_voltage() can return
rdev->desc->fixed_uV without .list_voltage implementation.
