From 0bb423f2eaafedf89715c482a543dcd629ba3946 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 8 Feb 2019 14:45:20 +0100 Subject: ASoC: regulator notifier registration should be managed Regulator notifiers, that were registered during codec driver probing, must be unregistered during driver release, or device managed versions have to be used. This patch fixes codec drivers, that weren't explicitly unregistering notifiers and simplifies those, that did that manually.
