I ran checkpatch.pl on patches that contains .c files and .h files and I 
had fixed lot of style related warnings using checkpatch.pl.

However, I had misunderstanding that checkpatch.pl should not be used 
for patches with .yaml and .dtsi files.

So I skipped it for bindings patch and dtsi patch. Thanks for correcting 
me here. I will make sure to run checkpatch.pl for all patches from 
here. Also, I will fix this error in next revision.
