From 942bfb3ed08b677e0a447096c501d6b0b49f44f9 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 17 Dec 2012 16:02:27 -0800 Subject: drivers/rtc/rtc-test.c: avoid calling platform_device_put() twice In case of error, test_init() needs to call platform_device_del() instead of platform_device_unregister(). Otherwise, we may call platform_device_put() twice. dpatch engine is used to auto generate this patch.
