From a6f1086e29e93621a6394b94b8c0e4a4e490f38b Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 5 Mar 2018 15:22:30 -0800 Subject: PCI: Move of_irq_parse_and_map_pci() declaration under OF_IRQ Since commit 4670d610d592 ("PCI: Move OF-related PCI functions into PCI core"), sparc:allmodconfig fails to build with the following error. pcie-cadence-host.c:(.text+0x4c4): undefined reference to `of_irq_parse_and_map_pci' pcie-cadence-host.c:(.text+0x4c8): undefined reference to `of_irq_parse_and_map_pci' of_irq_parse_and_map_pci() is now only available if OF_IRQ is enabled. Make its declaration and its dummy function dependent on OF_IRQ to solve the problem.
