From 8e6bfb9b1f79e07c18b0ae406c7c678fc54e4d8e Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Thu, 10 Feb 2011 13:24:32 +0100 Subject: ASoC: CX20442: fix wrong reg_cache_default content Content of the CX20442's snd_soc_codec_driver.reg_cache_default pointed area, introduced with my recent NULL pointer dereferece fix (commit f019ee5feb344ff0b22b58df4568676295aae14f), occured wrong after further testing, more thorough than just booting successfully. There are two problems with it: 1) It should read (1 << CX20442_TELOUT) | (1 << CX20442_MIC), not CX20442_TELOUT | CX20442_MIC. 2) While correctly matching actual codec hardware state on boot when fixed per 1), a few more code modifications would still be required to reflect that state not only into register cache, but also force them into DAPM pins state, otherwise an inconsitency occures which may prevent further codec state changes from being applied correctly. As a result, the phone stops ringing after reboot, until someone picks up the handset for the first time. Revert that reg_cache_default content to a working, previous de facto default value of 0, in hope this change can still be accepted as an rc cycle fix.
