Commit Message

Bryan O'Donoghue Sept. 7, 2023, 4:44 p.m. UTC 
It is possible to pass all of the CAMSS subdevice internal operations
pointers from the controlling resources structure with an additional
pointer added to the resources structure.

This allows for the removal of most of the probe-time control structures.

I'd really vouch for adding commas at the end, so that the
next diffs will be smaller

otherwise
