[PATCH] iio: bme680_i2c: Make bme680_acpi_match depend on CONFIG_ACPI

From: Guenter Roeck
Date: Tue May 04 2021 - 13:40:25 EST


With CONFIG_ACPI=n and -Werror, 0-day reports:

drivers/iio/chemical/bme680_i2c.c:46:36: error:
'bme680_acpi_match' defined but not used

Reported-by: kernel test robot <lkp@xxxxxxxxx>

Given the other patch, question of course is if this ACPI ID
is real. A Google search suggests that this might not be the case.
Should we remove it as well ? STK8312 has the same problem.

Jonathan, I think this needs your input before I send more patches.
