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? Regards, Markus
