Subject[PATCH 1/2] remoteproc: Add __iomem to return of rproc_da_to_va.
The return value of rproc_da_to_va would probably be device memory. Add
__iomem annotation to it.

Signed-off-by: Pi-Hsun Shih <>
I feel that there might be more things that need to be changed
(especially for the carveouts things). I didn't change them since I
don't know how to test that part. Comments needed.
