The commit doesn't match the patch.  Also this driver is in
staging because it's going to be deleted soon so there probably isn't
much point doing cleanups.

If you're looking at the Smatch resource_size() message, then that's a
tricky thing because of the + 1 on part of the "end - start + 1"...
It's sometimes hard to know if we should add the + 1 which resource_size()
does or not.  (That check is ancient and not up to modern standards).

No, the driver just came back in staging since I fixed the videobuf2 conversion.
One of the reason it is kept in staging is that media maintainer want to test it with its own zoran card but covid19 delayed the physical recovery of it.

So the patch need to be resent, please.
