Subject: [PATCH 07/15] PCI: v3: Use pci_host_probe() to register host
Date: Fri, 22 May 2020 17:48:24 -0600	[thread overview]
Message-ID: <20200522234832.954484-8-robh@kernel.org> (raw)
In-Reply-To: <20200522234832.954484-1-robh@kernel.org>

The v3 host driver does the same host registration and bus scanning
calls as pci_host_probe, so let's use it instead.
