From f019ee5feb344ff0b22b58df4568676295aae14f Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Tue, 1 Feb 2011 13:01:17 +0100 Subject: [PATCH] ASoC: CX20442: fix NULL pointer dereference The CX20442 codec driver never provided the snd_soc_codec_driver's .reg_cache_default member. With the latest ASoC framework changes, it seems to be referred unconditionally, resulting in a NULL pointer dereference if missing. Provide it.
