[PATCH v2 3/3] PCI: ultrarisc: allow DP1000 driver to build as module

[Jia Wang via B4 Relay]

From: Jia Wang <wangjia@xxxxxxxxxxxxx>

CONFIG_PCIE_ULTRARISC is a tristate option, so the driver can be selected
as a module when COMPILE_TEST or platform configuration allows it.  Using
builtin_platform_driver() leaves the module build without the module
init/exit plumbing and causes modpost failures for the generated .ko.

Use module_platform_driver() so the driver works for both module and
built-in builds while keeping the existing tristate Kconfig entry.

Fixes: 5fc35740c3b3 ("PCI: ultrarisc: Add UltraRISC DP1000 PCIe Root Complex driver")
