From 3e217b660281bbdf2db7e58725a4934b5635cb46 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 29 Apr 2013 16:18:27 -0700 Subject: rtc: add devm_rtc_device_{register,unregister}() These functions allow the driver core to automatically clean up any allocation made by rtc drivers. Thus it simplifies the error paths.

Thus, in order to sync with other devm_* functions, struct device is used as the first argument for devm_rtc_device_register().
