Re: [alsa-devel] [asoc:for-4.20 333/424] sound/pci/hda/patch_ca0132.c:7650:20: error: implicit declaration of function 'pci_iomap'; did you mean 'pcim_iomap'?

Hrm, the header file inclusion of pci_iomap() looks fairly inconsistent over architectures. SH doesn't include asm/pci_iomap.h from asm/io.h. And x86 includes it from linux/io-mapping.h.

As a quick fix, we can just include <asm/pci_iomap.h> from patch_ca0132.c, I suppose.

Not on x86 we can't, it's not there - asm/io.h seems safest AFAICT, everyone has it and both SH and x86 include the pci_iomap.h.
