Subject: [PATCHv4 11/28] PCI: mobiveil: only fix up the Class Code field
Date: Mon, 11 Mar 2019 09:31:23 +0000 [thread overview]
Message-ID: <20190311093130.7209-12-Zhiqiang.Hou@nxp.com> (raw)
In-Reply-To: <20190311093130.7209-1-Zhiqiang.Hou@nxp.com>
From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>
Fix up the Class Code to PCI bridge, do not change the Revision ID.
And move the fixup to mobiveil_host_init function.
Fixes: 9af6bcb11e12 ("PCI: mobiveil: Add Mobiveil PCIe Host Bridge
IP driver")
