Change pr_err/pr_debug statements to dev_err/dev_dbg for
increased clarity. Also clean up some return value checks.

'Also' on the commit message == 'split this to two'.
But here is a ping pong style of patches (you introduce a problem in

I'll do the ret value changes in the third patch in my next post, 
according to your comment there.

I'll try to avoid this in the next post
