[PATCH v2 0/2] Fixing bug that would segmentation fault

[Luiz Sampaio]

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.

Changes in v2:
- Changed return to -EINVAL and using WARN_ON as suggested 
- Note in response for Miguel's comment: for the first patch, I ran the
  script './scripts/checkpatch.pl --file --terse' to see with the file
had any coding style issue. That was when I was suggested to remove
'int' from 'unsigned long' declaration
