Subject: irqchip/gic-v3: Always return IRQ_SET_MASK_OK_DONE in gic_set_affinity
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0fc6fa2924d0dd54aa5c780a964c2812acf55ded;p=openwrt%2Fstaging%2Fblogic.git

irqchip/gic-v3: Always return IRQ_SET_MASK_OK_DONE in gic_set_affinity

Always return IRQ_SET_MASK_OK_DONE instead of IRQ_SET_MASK_OK when the
affinity has been updated. When using stacked irqchips, returning
IRQ_SET_MASK_OK_DONE means skipping all descendant irqchips.
