[PATCH 00/10] Tidy up device ID reading on legacy Cirrus parts

[Charles Keepax]

Pierre requested I have a look at some cppcheck warnings in the cs42l42
driver, since it is reassigning the ret variable without ever checking
the result.  Looking a bit more broadly this happens in quite a few
legacy Cirrus parts, as they all use the same process to read the ID,
factor out a small helper so they can all share the same code. Whilst
in there fix up a couple of other trivial error path issues as well.

Thanks,
Charles
