Subject[PATCH 4.4 056/124] regulator: pfuze100: add .is_enable() for pfuze100_swb_regulator_ops
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Anson Huang <Anson.Huang@nxp.com>

[ Upstream commit 0b01fd3d40fe6402e5fa3b491ef23109feb1aaa5 ]

If is_enabled() is not defined, regulator core will assume
this regulator is already enabled, then it can NOT be really
enabled after disabled.

Based on Li Jun's patch from the NXP kernel tree.
