So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/i2c/busses/i2c-xlr.ko | grep alias alias: platform:xlr-i2cbus After this patch: $ modinfo drivers/i2c/busses/i2c-xlr.ko | grep alias alias: platform:xlr-i2cbus alias: of:N*T*Csigma,smp8642-i2cC* alias: of:N*T*Csigma,smp8642-i2c Signed-off-by: Javier Martinez Canillas --- drivers/i2c/busses/i2c-xlr.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/i2c/busses/i2c-xlr.c b/drivers/i2c/busses/i2c-xlr.c index 0968f59b6df5..ad17d88d8573 100644 --- a/drivers/i2c/busses/i2c-xlr.c +++ b/drivers/i2c/busses/i2c-xlr.c @@ -358,6 +358,7 @@ static const struct of_device_id xlr_i2c_dt_ids[] = { }, { } }; +MODULE_DEVICE_TABLE(of, xlr_i2c_dt_ids); static int xlr_i2c_probe(struct platform_device *pdev) { -- 2.7.4
