[PATCH v3] console: newport_con: fix an issue about leak related system resources

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

   Subject:
   [PATCH v4] console: newport_con: Fix incomplete releasing of system resources

   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 iounmap() and release_mem_region()
     together with the check of a failure predicate.

   * Add also a call of release_mem_region() for the completion
     of resource clean-up on device removal.


It can be nicer if all patch reviewers (including me) will be explicitly specified
as recipients for such messages, can't it?

Markus
