2010-11-06ASoC: Decouple DAPM from CODECsLiam Girdwood
Decoupling Dynamic Audio Power Management (DAPM) from codec devices is required when developing ASoC further. Such as for other ASoC components to have DAPM widgets or when extending DAPM to handle cross-device paths. This patch decouples DAPM related variables from struct snd_soc_codec and moves them to new struct snd_soc_dapm_context that is used to encapsulate DAPM context of a device. ASoC core and API of DAPM functions are modified to use DAPM context instead of codec. This patch does not change current functionality and a large part of changes come because of structure and internal API changes. Core implementation is from Liam Girdwood <lrg@slimlogic.co.uk> with some minor core changes, codecs and machine driver conversions from Jarkko Nikula <jhnikula@gmail.com>.

2010-10-11ASoC: checking kzalloc() for IS_ERR() instead of NULLDan Carpenter
There is a typo here that got copy and pasted to several probe functions. kzalloc() returns NULL on allocation failures and not an ERR_PTR.
