If the driver is configured as a module (after allowing this by changing
PCIE_MICROCHIP_HOST from bool to tristate) the missing semicolon makes the
compiler very unhappy. While there isn't a real problem as
MODULE_DEVICE_TABLE always evaluates to nothing for a built-in driver,
do it right for consistency with other drivers.

Hello,

I wonder if there is a technical reason to have PCIE_MICROCHIP_HOST (and
some others) only bool. With this patch applied the driver compiles just
fine with PCIE_MICROCHIP_HOST=m.

Best regards
Uwe

I know ~nothing about the PCI driver itself, but I don't see why it wouldn't
work as a module. I gave it a try & nothing has blown up in my face so far...

works fine too. No particular reason to keep it bool.

For the record: I sent a patch to allow PCIE_MICROCHIP_HOST=m:
