Subject: [PATCH v2 0/5] irqchip/irq-vt8500: Cleanups and fixes for the
 irq-vt8500 driver

Fix the logic of ack/mask functions to actually do what their semantics
implies instead of lumping both actions into one. Also rework the chained
interrupts handling using common kernel infrastructure, while getting rid
of a boot-time WARN_ON due to a misplaced call to enable_irq.

Apparently neither edge-triggered interrupts nor chained interrupts had
any users, so nobody complained in 15 years.
