From 54e67e27394b997f72f6e2dbab98a11b6cd4c7d9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 3 Dec 2018 04:37:26 -0700 Subject: [PATCH] dm: sound: wm8994: Create a new common init function With driver model we cannot pass in the global struct, but instead want to pass in the driver-private data. Split some of the code out of wm8994_init() to handle this.
