ARM: Bulk conversion to generic_handle_domain_irq()
Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq(). Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: Marc Zyngier <maz@kernel.org>
