[PATCH] ASoC: wcd9335: remove redundant use of ret variable

From: Saiyam Doshi
Date: Mon Sep 09 2019 - 13:45:58 EST


All these functions declares and initializes variable ret with
'0' and without modifying 'ret' variable, it is returned.

This patch removes this redundancy and returns '0' directly.
