-Subject: gpio: Add helpers to ease the transition towards immutable irq_chip
-
-From: Marc Zyngier <maz@kernel.org>
-
-[ Upstream commit 36b78aae4bfee749bbde73be570796bfd0f56bec ]
-
-Add a couple of new helpers to make it slightly simpler to convert
-drivers to immutable irq_chip structures:
-
-- GPIOCHIP_IRQ_RESOURCE_HELPERS populates the irq_chip structure
- with the resource management callbacks
-
-- gpio_irq_chip_set_chip() populates the gpio_irq_chip.chip
- structure, avoiding the proliferation of ugly casts

-
-In order to move away from gpiolib messing with the internals of

-that they are not to be messed with, and do solemnly swear that
-they correctly call into the gpiolib helpers when required.
