Subject: [PATCH 0/2] Fixing bug that would segmentation fault

This series of patches consists of one patch fixing a simple coding style
issue and one patch fixing a bug that would cause segmentation fault.
Basically, there was a pointer that was being dereferenced without testing
if the pointer exists. This patch adds a protection, returning EFAULT in
case the pointer is NULL.

    dereferencing
