[PATCH] regulator: s2mps11: Fix GPIO descriptor initialization

From: Marek Szyprowski
Date: Tue Nov 20 2018 - 07:39:02 EST


GPIO descriptor array must be zero initialized to ensure that core will
properly handle also the case when no external GPIO pin is defined.

Fixes: 1c984942f0a4 ("regulator: s2mps11: Pass descriptor instead of GPIO number")
