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.
Is this a problem unique to the SSI driver? Maybe devm_free_irq() should also dispose of the mapping?
If the mapping was not created by the device, the device shouldn't dispose it. Mapping and requesting the interrupt are two independent operations.
