From 5efe89d9525f24f607079307d2d9510e30ba8590 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 30 Oct 2014 21:01:09 +0100 Subject: [PATCH] ASoC: wm9713: Move driver state struct allocation to driver probe Resources for the device should be allocated in the device driver probe callback, rather than in the ASoC CODEC probe callback. E.g. one advantage is that we can use device managed allocations.
