Subject: regulator: s2mps11: Fix GPIO descriptor initialization
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d7c7fc442fa6f6f0cd0115d7b8dbdf6fe2eeea44;p=openwrt%2Fstaging%2Fblogic.git

regulator: s2mps11: Fix GPIO descriptor initialization

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")
