From 299ac44422fbe7ff23ff1f01667cfe87bc61c74a Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 15 Sep 2016 02:20:43 +0000 Subject: [PATCH] staging: android: ion: Fix return value check in hi6220_ion_probe() In case of error, the function ion_device_create() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
