[PATCH] net: wan: wanxl.c: Cleaning up declaration of a while loop
From: Rickard Strandqvist
Date: Sat Jun 07 2014 - 07:03:19 EST
Unusual declaration of a while loop.
However, believe you also want to make sure that the pointer is not NULL
This was partly found using a static code analysis program called cppcheck.
