Subject: [PATCH 0/4] irqchip: Random irq_retrigger fixes
Date: Tue, 10 Mar 2020 18:49:17 +0000	[thread overview]
Message-ID: <20200310184921.23552-1-maz@kernel.org> (raw)

As I was investigating some ugly retrigger locking issues (see patch 4),
I managed to find three occurences of irq_retrigger callbacks that return
the wrong value, leading to a SW retrigger on top of the HW one.

Not really a big deal, but definitely worth fixing.

Marc Zyngier (4):
  irqchip/atmel-aic: Fix irq_retrigger callback return value
  irqchip/atmel-aic5: Fix irq_retrigger callback return value
  ARM: sa1111: Fix irq_retrigger callback return value
  irqchip/gic-v4: Provide irq_retrigger to avoid circular locking
    dependency
