[PATCH 03/12] staging: lustre: One function call less in class_register_type() after error detection

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 26 Jul 2016 13:40:47 +0200

The kobject_put() function was called in a few cases by the
class_register_type() function during error handling even if the passed
data structure element did not contain a pointer for a valid data item.

Adjust jump targets according to the Linux coding style convention.
