Granted, dealing with the patch conflicts aren't that hard, but the cost/benefit ratio isn't worth it. For kernel newbies who are looking for practice submitting patches, cleaning up checkpatch warnings in the staging subsystem are fine, but in general, it's best to not send cleanup-only patches to other parts of the system. Of course, if you're modifying that part of the code in question, that's a perfect time to clean it up while you're at it. > Removed trailing whitespaces introduced in v1 In the future, please put changes between the v1 and v2 patches after the three hyphens (by where the summary of how many lines were added or removed in each file). That way the description of changes between earlier versions aren't preserved forever in the git commit description, since they aren't really useful once they've landed in the git. Thanks, - Ted
