Subject: [GIT PULL] irqchip fixes for 5.16, take #1

Hi Thomas,

Here's a small set of fixes for 5.16.

The most interesting one is a fix for the SiFive PLIC, which happens
to ignore an EOI if the interrupt has been masked during the
handling. Ouch. We also have a fix for the csky interrupt controller
which was mixing mask/unmask with disabled/enabled, and a another for
a regression in the OF irq parsing (this last one is carrying Rob's
 Reviewed-by: tag).

Note that the branch is on the same base as tip/irq/urgent
(debe436e77c7).

Please pull,

	M.

  of/irq: Don't ignore interrupt-controller when interrupt-map failed (2021-11-12 16:10:00 +0000)

----------------------------------------------------------------
irqchip fixes for 5.16, take #1

- Address an issue with the SiFive PLIC being unable to EOI
  a masked interrupt

- Move the disable/enable methods in the CSky mpintc to
  mask/unmask

- Fix a regression in the OF irq code where an interrupt-controller
  property in the same node as an interrupt-map property would get
  ignored
