Subject[PATCH 1/2] irqchip/irq-brcmstb-l2: Set IRQ_LEVEL for level triggered interrupts
Date
When support for the level triggered interrupt controller flavor was
added with c0ca7262088e, we forgot to update the flags to be set to
contain IRQ_LEVEL. While the flow handler is correct, the output from
/proc/interrupts does not show such interrupts as being level triggered
when they are, correct that.

Fixes: c0ca7262088e ("irqchip/brcmstb-l2: Add support for the BCM7271 L2 controller")
