From 10e7ff0047921e32b919ecee7be706dd33c107f8 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 3 Jun 2022 14:25:26 +0200 Subject: ASoC: wcd938x: Fix event generation for some controls Currently wcd938x_*_put() unconditionally report that the value of the control changed, resulting in spurious events being generated. Return 0 in that case instead as we should. There is still an issue in the compander control which is a bit more complex.
