Subject: [PATCH v3 06/15] s390x/pci: Remove a ptr to S390PCIBusDevice from S390PCIIOMMU
Date: Thu, 4 Jun 2026 21:17:19 -0500 [thread overview]
Message-ID: <20260605021728.1125090-7-kshk@linux.ibm.com> (raw)
In-Reply-To: <20260605021728.1125090-1-kshk@linux.ibm.com>
This pointer is no longer used, after fields were moved from S390PCIIOMMU
to S390PCIBusDevice.
