[PATCH] PCI: build Broadcom PAXC quirks unconditionally

[PATCH] PCI: build Broadcom PAXC quirks unconditionally

[Wei Liu]

CONFIG_PCIE_IPROC_PLATFORM only gets defined when the driver is built
in.  Removing the ifdef will allow us to build the driver as a module.

Signed-off-by: Wei Liu <wei.liu@kernel.org>
---
Alternatively, we can change the condition to:

  #ifdef CONFIG_PCIE_IPROC_PLATFORM || CONFIG_PCIE_IPROC_PLATFORM_MODULE
.

I chose to remove the ifdef because that's what other quirks looked like
in this file.

Sorry, I missed this thinking it would be under drivers/pci/controller
and hence handled by Lorenzo.

So I guess this doesn't fix a build problem, but without this patch,
we just don't run the quirk if the driver is a module, right?

Yes, this is correct.

Without this patch, the quirk doesn't get to run if the driver is a module.

Hi Bjorn

Are you satisfied with the patch? What do I need to do to get it merged?

You needn't do anything.  I'll clarify the changelog (the patch
doesn't actually *enable* building the driver as a module; it merely
ensures that we include the quirk in that case).

This is too late for v5.5, so it will get merged for v5.6 unless the
modular driver itself was enabled for v5.5.

Is there a reason this quirk can't be moved to
drivers/pci/controller/pcie-iproc-platform.c?  That would make it much
less subtle because it would be compiled if and only if the driver
itself is compiled.

If it needs to be here in quirks.c, please include a note about the
reason.

There's no particular reason and yes it could be moved to pcie-iproc.c.

If that's preferred (and it sounds like it is) then we can do that.

Yes, please, that would be great!  No #ifdefs, plus the code won't be
compiled into x86 and other arches that never use that driver.

Okay, Wei, let me know if you'd like to help with that? If not, I can 
make the change.
