Hi Greg,
Thanks for your reply.
Actually, I'm following the Eudyptula Challenge and I'm at task 10.
Task is to find and fix a coding style in linux-next/drivers/staging.
I've checked many files with checkpatch.pl but they are almost fine :)
I found this one and prepared a patch for it.
Thanks in advance for your comments and advice.
Thanks,
Fatih
