[PATCH 1/3] regulator: pfuze100-regulator: Remove global variable

From: Fabio Estevam
Date: Sun Jun 05 2016 - 18:19:53 EST


From: Fabio Estevam <fabio.estevam@xxxxxxx>

We should better not use a global 'struct pfuze_regulator' variable,
as this could cause problems if multiple regulator chips are used.

Place it inside the private struct instead.
