From e0799c04b2080e0832538a911361f962c93fb744 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 23 Feb 2011 14:10:54 +0100 Subject: [PATCH] x86: ioapic: Use setup function in __io_apic_set_pci_routing() The only difference here is that we did not call __add_pin_to_irq_node() for the legacy irqs, but that's not worth 30 lines of extra code.
