Hi Frank,

Right, the commit message was stale from an earlier version that used
devm_irq_domain_instantiate() with an open-coded irq_domain_info. I'll
fix it in v7 to describe the actual change (irq_domain_create_linear()
-> devm_irq_domain_create_linear(), dropping irq_domain_remove() in
remove()).

Thanks,
