Subject: [PATCH 5/6] md: Adjust six function calls together with a variable
 assignment in faulty_status()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 2 May 2017 15:35:35 +0200

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix the affected source code places.
