From 3943b9efb381531b99bf9c545736f9e1e2715b9c Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 5 Oct 2015 21:23:48 +0800 Subject: [PATCH] ASoC: rt298: Make rt298_index_def const The index_cache is per instance run time state but rt298_index_def is not. Make rt298_index_def const and make a copy of memory for index_cache rather than directly use the rt298_index_def.
