[PATCH] arch: cris: arch-v32: drivers: axisflashmap.c: Cleaning up inconsistent NULL checks
From: Rickard Strandqvist
Date: Thu May 22 2014 - 17:59:23 EST
Cleaning up inconsistent NULL checks.
There is otherwise a risk of a possible null pointer dereference.
Was largely found by using a static code analysis program called cppcheck.
