This change

e23bd83368af ("firmware: stratix10-svc: fix kernel-doc markups")

Makes a lot of formatting changes in the same files as this patchset, including the first patch.

It would be good to try applying this patchset to char-misc-next and resubmit if there are conflicts.

These changes look good to me.

I was looking at the patchset again seeing if the firmware/ parts could be split out.

Even though stratix10 is a fpga, from the MAINTAINERS file it is not clear to me if linux-fpga owns them and they come in on Moritz's branch.  I think this change is needed to the MAINTAINERS file to make that clearer.

I also added myself as a reviewer because I want to help out.
