4.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd@xxxxxxxx> commit 1e73359a24fad529b0794515b46cbfff99e5fbe6 upstream. When building without CONFIG_PCI, we can (depending on the architecture) get a link failure: ERROR: "pci_iounmap" [sound/pci/hda/snd-hda-codec-ca0132.ko] undefined! Adding a compile-time check for PCI gets it to work correctly on 32-bit ARM.
