From 97d8a6970a3da5856633f2a705f0687fca4af9a5 Mon Sep 17 00:00:00 2001 From: Pratyush Yadav Date: Thu, 24 Sep 2020 10:04:11 +0530 Subject: [PATCH] regmap: zero out the regmap on allocation Some fields will be introduced in the regmap structure that should be set to 0 by default. So, once we allocate a regmap, make sure it is zeroed out to avoid unexpected defaults for those values.
