Use dev_err() which will going to print the driver's name as well and the
KERN_ERR level is sufficient in this case (we also print via dev_err when
there is an error with the mem resources)

So this one change in the log level. If I look at now, may be dev_err
is fine but the change is not same.

Apart from above comment, rest of the series looks fine to me.
Feel free to add my ack...

Not sure what you mean by 'the change is not same'?
I just picked the old series and rebased it on linux-next, the patch is the
same as it was back in May 2013:
https://lkml.org/lkml/2013/5/2/205

And yes, I have shortened the texts in the print, but the meaning of the
prints have not changed.
