[Sound-open-firmware] checkpatch.pl fixes

[Daniel Baluta]

Hi all,

What is your take on checkpatch.pl fixes for SOF FW?

Diana (CC'ed) is trying to get accustomed with SOF code
and while at that she can fix some obvious checkpatch.pl
warn / errors.

Does it make sense to send some patches for that?

I know that this kind of fixes can pollute the change
history but on the other side code gets a little bit cleaner.

thanks,
Daniel.
