Add support for debug_dma_mapping_error() call to avoid warning from
debug_dma_unmap() interface when it checks for mapping error checked
status. Without this patch, device driver failed to check map error
warning is generated.

Looks good. Similar fix for 32bit ARM port is done in below commit.

The patch looks fine but debug_dma_mapping_error() is not in mainline
yet, so it will have to wait. If you want to add it to your series
(which I assume adds debug_dma_mapping_error() support), you can add
my Acked-by on the patch.

Do you want this patch going through linux-next or the ARM64 tree? Let
me know your preference.

I think it can go together with your other patches since I can't tell
when you'll push the debug_dma_mapping_error() implementation.

Marek,
This one is for ARM64 and ARM tree has already been fixed.
