From 50b9ac1813f7f2f13c937a1484c2fe09c4d590ce Mon Sep 17 00:00:00 2001 From: Rickard Strandqvist Date: Sun, 1 Jun 2014 01:00:13 +0200 Subject: arch: tile: kernel: unaligned.c: Cleaning up uninitialized variables There is a risk that the variable will be used without being initialized. This was largely found by using a static code analysis program called cppcheck.
