[OpenWrt-Devel] [PATCH] bcm63xx: Report that effective affinity is a single target

[Daniel Gonzalez Cabanelas]

The bcm6345-periph-intc driver only targets a single CPU at a time, even if
the notional affinity is wider. Let's inform the core code about this.

This patch gets rid of the kernel message:
"genirq: irq_chip bcm6345-periph-intc did not update eff.
affinity mask of irq 52"
