Yes. Part of the Acked-by tag is actually unspecified Acknowledgment and
many maintainers do not trail it with "# subpart" name. It's well
accepted and known in our community that Acked-by can be for everything
or for Maintainer's responsible area, implied by MAINTAINERS file.

Reviewed-by even with the "# subpart" still appears in person's credits
and reviewing entire patch of 700 lines of diff code (like Frank's SPI
patch) is not the same as 10 diff codes for one driver.

I'll send later v3 with the changes from above.
