Subject: [PATCH 09/15] PCI: xgene: Use pci_host_probe() to register host
Date: Fri, 22 May 2020 17:48:26 -0600	[thread overview]
Message-ID: <20200522234832.954484-10-robh@kernel.org> (raw)
In-Reply-To: <20200522234832.954484-1-robh@kernel.org>

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