Under certain build conditions, the following warning is being generated
from the isl29501 driver due to OF being configured but the driver being
built in.
drivers/iio/proximity/isl29501.c:999:34: warning: ‘isl29501_i2c_matches’ defined but not used [-Wunused-const-variable=]
999 | static const struct of_device_id isl29501_i2c_matches[] = {
The isl29501_i2c_matches[] is only passed to MODULE_DEVICE_TABLE() and thus is
not referenced if the driver is built into the kernel. Fix by adding a check
for MODULE around the #if block.
