[PATCH 05/12] staging: lustre: Optimize error handling in class_register_type()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 26 Jul 2016 14:23:23 +0200

Return a constant error code without storing it in the local variable "rc"
after a failed memory allocation at the beginning of this function.
