--------------------------------
[ Upstream commit 6a0b8c0da8d8d418cde6894a104cf74e6098ddfa ]
The arche-ctrl has two platform drivers and three of_device_id tables, but one table is only used for the the module loader, while the other two seem to be associated with their drivers.
This leads to a W=1 warning when the driver is built-in:
drivers/staging/greybus/arche-platform.c:623:34: error: 'arche_combined_id' defined but not used [-Werror=unused-const-variable=] 623 | static const struct of_device_id arche_combined_id[] = {
Drop the extra table and register both tables that are actually used as the ones for the module loader instead.
