Below is a version of this patch against Linus' tree, with the SFFSDR board changes from Hugo included. Kevin [1] http://git.kernel.org/?p=linux/kernel/git/khilman/linux-davinci.git;a=summary commit 53748f550f8dcd2cad676e67804d69cd4424ab4f Author: Chaithrika U S <chaithrika@xxxxxx> Date: Fri Feb 13 12:39:39 2009 +0530 ASoC: DaVinci: fix module unload error Fix for the error when the audio module is unloaded. On unregistering the platform_device, platform_device_release will free the platform data.If platform data is static the kernel panics when it is freed. Instead use the platform device helper function to add data. This change has been tested on DM644x EVM, DM644x SFFSDR and DM355 EVM.
