From 08ac260f36b4c11eb33fa58466462a5e1027bdb3 Mon Sep 17 00:00:00 2001 From: Yue Hu <zbestahu@gmail.com> Date: Thu, 14 Feb 2019 19:34:16 +0800 Subject: [PATCH] pstore/ram: Avoid possible failure of dummy device unregister
If create dummy platform device failed, dummy variable should not been set as NULL. Because the following platform_device_unregister() will judge if the dummy is NULL or not, if dummy is NULL nothing happen for unregister flow.
