Subject: genirq: Rename setup_affinity() to irq_setup_affinity()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=43564bd97d0e6182bbd43b51b33254c728832551;p=openwrt%2Fstaging%2Fblogic.git

genirq: Rename setup_affinity() to irq_setup_affinity()

Rename it with a proper irq_ prefix and make it available for other files
in the core code. Preparatory patch for moving the irq affinity setup
around.
