From a43ae58c848cfbadaba81c8d63202b4487f922a0 Mon Sep 17 00:00:00 2001 From: Hanjun Guo Date: Tue, 6 May 2014 11:29:52 +0800 Subject: PCI: Turn pcibios_penalize_isa_irq() into a weak function pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA is not used by some architectures. Make pcibios_penalize_isa_irq() a __weak function to simplify the code. This removes the need for new platforms to add stub implementations of pcibios_penalize_isa_irq().
