From 25d0d35ed7d4ded4ba90e6311c80f2eca65d12f0 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 27 Oct 2014 16:11:54 +0800 Subject: x86, irq: Kill useless parameter 'irq_attr' of IO_APIC_get_PCI_irq_vector() None of the callers requires irq_attr to be filled in. IO_APIC_get_PCI_irq_vector() does not do anything useful with it either. Remove the parameter and fixup the call sites.
