Subject: [PATCH 0/3] PCI: Modularize host-generic
Date: Thu,  9 Apr 2020 17:49:20 -0600	[thread overview]
Message-ID: <20200409234923.21598-1-robh@kernel.org> (raw)

This is part of a larger effort to modularize ARCH_VEXPRESS. In
particular, the Arm FVP platforms use the host-generic driver. This
conversion was straight-forward. I didn't convert the other ECAM drivers
using host-common to modules, but am happy to do so if there's a strong
desire to do so.

In the process, I noticed that 'const' was being dropped from the match
table .data pointer, so the first patch constifies struct pci_ecam_ops.
I started trying to constify pci_ops too, but that became a never ending
treewide rabbit hole. So I ended up with a cast when we assign pci_ops
from pci_ecam_ops.
