Subject: [PULL 19/32] xen/pt: Fix flawed conversion to realize()
Date: Wed, 29 Apr 2020 09:20:35 +0200 [thread overview]
Message-ID: <20200429072048.29963-20-armbru@redhat.com> (raw)
In-Reply-To: <20200429072048.29963-1-armbru@redhat.com>
The conversion of xen_pt_initfn() to xen_pt_realize() blindly replaced
XEN_PT_ERR() by error_setg(). Several error conditions that did not
fail xen_pt_initfn() now fail xen_pt_realize(). Unsurprisingly, the
cleanup on these errors looks highly suspicious.
Revert the inappropriate replacements.
