devm_request_irq() is used by other drivers too, this should not be a problem. Looking at the code it seems that irq_dispose_mapping may not be necessary with devm_request_irq(). So I think it would be better to remove irq_dispose_mapping() instead.
The driver creates the mapping by calling irq_of_parse_and_map(), so it also has to dispose the mapping. But the easy way out is to simply use platform_get_irq() instead of irq_of_parse_map(). In this case the mapping is not managed by the device but by the of core, so the device has not to dispose the mapping.
