mcb: Replace ioremap and request_region with the devm version
Replaced ioremap with devm_ioremap and request_mem_region with devm_request_mem_region. This makes the code much more cleaner. Signed-off-by: Andreas Werner <andreas.werner@men.de> Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
