[PATCH 4.14-openela 045/190] PCI: keystone: Don't discard .probe() callback

[Sasha Levin <sashal@kernel.org>]

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

[ Upstream commit 7994db905c0fd692cf04c527585f08a91b560144 ]

The __init annotation makes the ks_pcie_probe() function disappear after
booting completes. However a device can also be bound later. In that case,
we try to call ks_pcie_probe(), but the backing memory is likely already
overwritten.

The right thing to do is do always have the probe callback available.  Note
that the (wrong) __refdata annotation prevented this issue to be noticed by
modpost.

Fixes: 0c4ffcfe1fbc ("PCI: keystone: Add TI Keystone PCIe driver")
