From d050d53b9e38bcda93b787b60e1428c7ebe8ce8d Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 28 Jun 2013 09:53:41 +1000 Subject: [PATCH] drivers/rtc/rtc-twl.c: fix rtc_reg_map initialization Initialize the rtc_reg_map in platform_driver's probe function instead at module_init time. 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 its init.
