[PATCH -next] firmware: google memconsole: Fix return value check in platform_memconsole_init()

From: Wei Yongjun
Date: Mon Apr 24 2017 - 23:12:03 EST


From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

In case of error, the function platform_device_register_simple() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().

Fixes: d384d6f43d1e ("firmware: google memconsole: Add coreboot support")
