[PATCH 9/13] md/multipath: Adjust two function calls together with a variable assignment

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 2 Oct 2016 10:05:43 +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.
