Subject: [PATCH v12 05/15] PCI/ERR: Simplify by using pci_upstream_bridge()
Date: Fri, 20 Nov 2020 16:10:26 -0800	[thread overview]
Message-ID: <20201121001036.8560-6-sean.v.kelley@intel.com> (raw)
In-Reply-To: <20201121001036.8560-1-sean.v.kelley@intel.com>

Use pci_upstream_bridge() in place of dev->bus->self.  No functional change
intended.

[bhelgaas: split to separate patch]
