Subject: [PULL 18/20] s390x: protvirt: Fix stray error_report_err in s390_machine_protect
Date: Thu, 30 Apr 2020 11:44:43 +0200	[thread overview]
Message-ID: <20200430094445.25943-19-cohuck@redhat.com> (raw)
In-Reply-To: <20200430094445.25943-1-cohuck@redhat.com>

From: Janosch Frank <frankja@linux.ibm.com>

In case the protection of the machine fails at s390_pv_vm_enable(),
we'll currently report the local_error variable. Problem is that
there's no migration blocker error that we can report at this point so
the pointer is always NULL which leads to a SEGFAULT.

Let's remove the error report.
