[PATCH -next] staging: android: ion: Fix return value check in hi6220_ion_probe()

From: Wei Yongjun
Date: Wed Sep 14 2016 - 22:21:00 EST


From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

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().
