| |
From: Arnd Bergmann <arnd@arndb.de>
When the driver is built-in, it produces a W=1 warning:
drivers/comedi/drivers/ni_atmio.c:209:35: error: 'device_ids' defined but not used [-Werror=unused-const-variable=] 209 | static const struct pnp_device_id device_ids[] = {
The actual probe() function has a different way of identifying the hardware, so just mark this one as __maybe_unused so it can be dropped when built-in.
