This series is a follow-up to [1]. Some users of irq_alloc_generic_chip() are modules which can be removed (e.g. gpio-ml-ioh) but have no means of freeing the allocated generic chip. Last time it was suggested to provide irq_destroy_generic_chip() which would undo both irq_remove_generic_chip() and irq_alloc_generic_chip(). This functionality is provided by patch 2/5 with 1/5 adding the option to only free the allocated memory. Patch 3/5 exports a function that will be used in the devres variant of irq_alloc_generic_chip(). Patches 4/5 and 5/5 add resource managed versions of irq_alloc_generic_chip() & irq_setup_generic_chip(). They will be used in drivers where applicable. Device resources are released in reverse order so it's ok to call devm_irq_alloc_generic_chip() and then devm_irq_setup_generic_chip().
