Subject: [PATCH v4 1/5] s390x/ap: fix missing subsystem reset registration
Date: Wed, 23 Aug 2023 16:22:15 +0200 [thread overview]
Message-ID: <20230823142219.1046522-2-seiden@linux.ibm.com> (raw)
In-Reply-To: <20230823142219.1046522-1-seiden@linux.ibm.com>
From: Janosch Frank <frankja@linux.ibm.com>
A subsystem reset contains a reset of AP resources which has been
missing. Adding the AP bridge to the list of device types that need
reset fixes this issue.
