This way we can make sure that the twl-core has been already probed and initialized (twl_priv->twl_id is valid) since the platform device for the RTC driver will be created by the twl-core after it finished it's init. Reported-by: Christoph Fritz Signed-off-by: Peter Ujfalusi --- Hi, As Tomi commented on the first version: www.spinics.net/lists/linux-omap/msg90064.html www.spinics.net/lists/linux-omap/msg90066.html I have separated the actual fix from the module_platform_driver() conversion.
