Fixed many checkpatch.pl complaints, ranging from whitespace issues to
reportedly deprecated function and macro usage.
I have not been able to test the code as I do not have access to the
hardware but since no new features were really added I don't think that
should pose a problem.
There are still some checkpatch complaints, particularly concerning
potentially unnecessary 'out of memory' messages. I will provide patches
for these complaints when I figure out the reason behind it and what to
do about it.
NOTE: This is my first patch (ever). I have attempted to follow all
guidelines provided, but I probably will have missed some. If you have
any comments regarding the quality of this patch or suggestions as to
what I could do better in the future, please let me know.
