The driver can be compile tested with !CONFIG_OF or !CONFIG_ACPI making unused. This fixes compile tests with W=1 by annotating device ID table as possibly unused: drivers/char/tpm/st33zp24/i2c.c:141:34: error: ‘of_st33zp24_i2c_match’ defined but not used [-Werror=unused-const-variable=] drivers/char/tpm/st33zp24/spi.c:258:34: error: ‘of_st33zp24_spi_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <redacted> --- Changes since v1: 1.
