[PATCH 00/14] ppc/spapr: Error handling fixes and cleanups

[Greg Kurz]

This series aims to be a follow up to Markus Ambruster's massive
work to sanitize error handling. It focuses on the following:
- check return values rather than a pointer to a local Error object
- get rid of the local_err + error_propagate() boilerplate when
  possible
- propage negative errnos to vmstate instead of -1
