From 898673b905b9318489430663083f629bc38c7461 Mon Sep 17 00:00:00 2001 From: Simon Trimmer Date: Fri, 21 Jul 2023 14:21:10 +0100 Subject: ASoC: cs35l56: Move shared data into a common data structure The ASoC and HDA drivers have structures that contain some of the same information - instead of maintaining two locations for this data the drivers should share a common data structure as this will enable common utility functions to be created. The first step is to move the location of these members in the ASoC driver.
