c980983dae irqchip/mvebu-odmi: Switch to bitmap_zalloc()
Switch to bitmap_zalloc() to show clearly what we are allocating.
Besides that it returns pointer of bitmap type instead of opaque void *.

0407daceed irqchip/gic: Return IRQ_SET_MASK_OK_DONE in the set_affinity method
Moving an SPI around doesn't require any extra work from the rest
of the stack, and specially not for MSI-generated SPIs.

It is then worth returning IRQ_SET_MASK_OK_DONE instead of
IRQ_SET_MASK_OK, and simplify the other irqchips that rely on
this behaviour (GICv2m and Marvell's ODMI controller).

c27f29bbbf irqchip/mvebu-odmi: Add new driver for platform MSI on Marvell 7K/8K
This commits adds a new irqchip driver that handles the ODMI
controller found on Marvell 7K/8K processors. The ODMI controller
provide MSI interrupt functionality to on-board peripherals, much like
the GIC-v2m.
