The driver can match by multiple methods. Its of_device_id table is referenced via of_match_ptr() so it will be unused for !CONFIG_OF builds: sound/soc/codecs/tlv320aic23-i2c.c:38:34: warning: ‘tlv320aic23_of_match’ defined but not used [-Wunused-const-variable=] sound/soc/codecs/tlv320adcx140.c:1076:34: warning: ‘tlv320adcx140_of_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20201125164452.89239-32-krzk@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>
