[PATCH 4.4 07/97] regulator: anatop: set default voltage selector for pcie

[Greg Kroah-Hartman]

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

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

From: Dong Aisheng <aisheng.d...@nxp.com>


[ Upstream commit 9bf944548169f6153c3d3778cf983cb5db251a0e ]

Set the initial voltage selector for vddpcie in case it's disabled
by default.

This fixes the below warning:
20c8000.anatop:regulator-vddpcie: Failed to read a valid default voltage 
selector.
anatop_regulator: probe of 20c8000.anatop:regulator-vddpcie failed with error 
-22
