From b2c812e22de88bb79c290c0e718280f10b64a48d Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 14 Apr 2010 15:35:19 +0900 Subject: ASoC: Add indirection for CODEC private data One of the features of the multi CODEC work is that it embeds a struct device in the CODEC to provide diagnostics via a sysfs class rather than via the device tree, at which point it's much better to use the struct device private data rather than having two places to store it. Provide an accessor function to allow this change to be made more easily, and update all the CODEC drivers are updated. To ensure use of the accessor the private data structure member is renamed, meaning that if code developed with older an older core that still uses private_data is merged it will fail to build.
