Hi; this change causes Coverity to complain (CID 1398591) that
we're now overwriting the setting of err in the earlier
err = spapr_rtc_import_offset(&spapr->rtc, spapr->rtc_offset);
without ever testing it. (We also do this in the existing
codepath that calls kvmppc_configure_v3_mmu().)
Should the call to spapr_rtc_import_offset() have its
own "if (err) do something" code, or should it simply
be ignoring its return value entirely, or something
more complicated ?
thanks
