The driver will match mostly or only by DT table (even thought there is regular ID table) so there is little benefit in of_match_ptr (this also allows ACPI matching via PRP0001, even though it might not be relevant here). drivers/net/dsa/lan9303_i2c.c:97:34: error: ‘lan9303_i2c_of_match’ defined but not used [-Werror=unused-const-variable=] drivers/net/dsa/lan9303_mdio.c:157:34: error: ‘lan9303_mdio_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/net/dsa/lan9303_i2c.c | 2 +- drivers/net/dsa/lan9303_mdio.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/net/dsa/lan9303_i2c.c b/drivers/net/dsa/lan9303_i2c.c index 1cb41c36bd47..e8844820c3a9 100644 --- a/drivers/net/dsa/lan9303_i2c.c +++ b/drivers/net/dsa/lan9303_i2c.c @@ -103,7 +103,7 @@ MODULE_DEVICE_TABLE(of, lan9303_i2c_of_match); static struct i2c_driver lan9303_i2c_driver = { .driver = { .name = "LAN9303_I2C", - .of_match_table = of_match_ptr(lan9303_i2c_of_match), + .of_match_table = lan9303_i2c_of_match, }, .probe_new = lan9303_i2c_probe, .remove = lan9303_i2c_remove, diff --git a/drivers/net/dsa/lan9303_mdio.c b/drivers/net/dsa/lan9303_mdio.c index 4f33369a2de5..d8ab2b77d201 100644 --- a/drivers/net/dsa/lan9303_mdio.c +++ b/drivers/net/dsa/lan9303_mdio.c @@ -164,7 +164,7 @@ MODULE_DEVICE_TABLE(of, lan9303_mdio_of_match); static struct mdio_driver lan9303_mdio_driver = { .mdiodrv.driver = { .name = "LAN9303_MDIO", - .of_match_table = of_match_ptr(lan9303_mdio_of_match), + .of_match_table = lan9303_mdio_of_match, }, .probe = lan9303_mdio_probe, .remove = lan9303_mdio_remove, -- 2.34.1
