[PATCH v2 07/13] memory: kill off set_irq_flags usage

From: robh@kernel.org (Rob Herring)
Date: 2015-07-12 14:29:10
Also in: linux-omap, lkml
Subsystem: memory controller drivers, omap general purpose memory controller support, the rest · Maintainers: Krzysztof Kozlowski, Roger Quadros, Tony Lindgren, Linus Torvalds

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.
