Subject: [PATCH 1/2] PCI: Call MPS fixup quirks early
Date: Thu, 24 Jun 2021 19:14:17 +0200	[thread overview]
Message-ID: <20210624171418.27194-1-kabel@kernel.org> (raw)

The pci_device_add() function calls header fixups only after
pci_configure_device(), which configures MPS.

So in order to have MPS fixups working, they need to be called early.

Signed-off-by: Marek Behún <kabel@kernel.org>
Fixes: 27d868b5e6cfa ("PCI: Set MPS to match upstream bridge")
