[PATCH] irqchip: mtk-sysirq: Skip setting irq-wake

[Markus Schneider-Pargmann]

mtk-sysirq doesn't require specific logic to work with wakeup IRQs. To
allow registered IRQs to be used as a wakeup-source, add the flag
IRQCHIP_SKIP_SET_WAKE.

Is this a fix? If so, please provide a Fixes: tag matching the commit
it addresses. Add a Cc stable if this requires backporting.

At least from my point of view I would like to prepare the mtk-sysirq
for powermanagement stuff, so not a fix. There may be some components
trying to use this already but I would consider this more of a feature
as it has probably never worked before.
Currently calls to enable_irq_wake() using IRQs of sysirq will result in
-ENXIO.

Thanks,
Markus

Fair enough. I'll keep that for 5.15 then.
