Subject: [PATCH 4.6 059/203] regulator: qcom_smd: add regulator ops for pm8941 lnldo

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

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

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

commit d1e44b6b2823f1751ffe7e7589f545f05cfe2095 upstream.

After "regulator: qcom_smd: add list_voltage callback" patch adding
pm8941 lnldo regulators would bug on list_voltages as it is a fixed
regulator without any linear range.
This patch fixes that issue by adding dedicated ops for pm8941 lnldo
without list_voltages callback.
