[PATCH] libnvdimm-btt: Delete an unnecessary check before the function call "__nd_device_register"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 24 Jul 2016 11:05:34 +0200

The __nd_device_register() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
