Subject: Re: [PATCH] drivers:pci Fix all whitespace issues

Hi Joe,
No this is not done with checkpatch.pl I just used it to verify that my changes are correct. I was wondering why that “type” pointer threw errors since it looks fine to me the way it was declared. This “type*” is just present in few of the files I can just redo those changes and send the patch again.

Thanks, Sasa
