Ok, I will post an updated patchset that adds sparc devm_irq_of_parse_and_map() that just calls irq_of_parse_and_map(), and devm_irq_dispose_mapping() that does nothing.
Also, you mentioned that some drivers that my original patchset touches are sparc-only? Then, maybe better not convert these to devm_? Could you please give a list of such drivers?
