From 4eea6fff612f54380dd642b045bf03ac0613fe3e Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Mon, 8 Jun 2009 03:32:15 -0700 Subject: [PATCH] x86/ioapic.c: clean up replace_pin_at_irq_node logic and comments There's no need for a control variable in replace_pin_at_irq_node(); it can just return if it finds the old apic/pin to replace. If the loop terminates, then it didn't find the old apic/pin, so it can add the new ones.
