Markus,
If you want to do something that might be useful, you could look into the problem of missing checks for dma mapping failure. There is nice slide presenatation about the issue:
http://www.slideshare.net/SamsungOSG/shuah-khan-dmamaperror
The slides are from a few years ago, but I did a small test recently, and the problem seems to persist. This needs to be done slowly and carefully, because when there is a failure, you need to figure out what to do to clean up and what value to return. There is no point to clean up all of the other checkpatch errors in the file at the same time. Just stay on the problem at hand.
