commit f151bb7ce45d7995c7fc4d3dd9df3f96cf637ffc Author: Juergen Gross <jgross@xxxxxxxx> AuthorDate: Tue Jun 7 14:16:49 2022 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Tue Jun 7 14:16:49 2022 +0200 tools/libs/ctrl: don't set errno to a negative value The claimed reason for setting errno to -1 is wrong. On x86 xc_domain_pod_target() will set errno to a sane value in the error case.
