I agree.  The patch is good.  My only comment was about the patch 
description.  You are fixing a coding style issue reported by smatch, 
not a NULL pointer dereference.  This is a code clean-up rather than a 
fix, but still the patch is just as useful.

While you are at it you could probably also incorporate the suggestion 
from Walter as that helps to improve the readability further.
