[PATCH v1] console: fix an issue about ioremap leak.

How do you think about a wording variant like the following?

   Subject:
   [PATCH v2] console: Complete exception handling in newport_probe()

   Change description:
   A call of the function “do_take_over_console” can fail here.
   The corresponding system resources were not released then.
   Thus add a call of the function “iounmap” together with the check
   of a failure predicate.


I would like to point out that there is a script for the semantic
patch language which would detect other questionable source code.

How do you think about to extend presented software analysis approaches?
