But I'll add some formatting comments. It looks like you have submitted a 2 patch series which fixes all the checkpatch errors in the vme_user driver? Kudos for separating out the 2 patches for the 2 different types of checkpatch errors! And for submitting a series which fixes the entire driver! But you should also include a cover letter for your series. How are you creating this series? Are you using 'git format-patch'? 'b4'? If not using 'b4' I strongly recommend it.[*] Both of those tools can help with formatting a cover letter and b4 will help keep track of multiple versions of the series as you fix things.
