I have a gpl driver for lsm202dlh which worked with 2.6 kernels. now in 3.5 I can modprobe it (after some include-changes), but after the echo command to new_device dmesg tells me
[ 1147.549042] lsm303dlh_a 6-0019: failed to get regulator [ 1147.549055] lsm303dlh_a 6-0019: probe function fails fffffdfb [ 1147.549067] i2c 6-0019: Driver lsm303dlh_a requests probe deferral [ 1147.549078] i2c i2c-6: new_device: Instantiated device lsm303dlh_a at 0x19 and some kind of generic files in sysfs are created but not the ones that driver should create. the driver does obviously do ddata->regulator = regulator_get(&client->dev, "vdd"); if (IS_ERR(ddata->regulator)) { dev_err(&client->dev, "failed to get regulator\n"); ret = PTR_ERR(ddata->regulator); ddata->regulator = NULL; goto err_op_failed; } ... err_op_failed: kfree(ddata); err_alloc: dev_err(&client->dev, "probe function fails %x", ret); return ret; so my question is, what is the meaning of fffffdfb being returned from regulator_get(dev,"vdd")? is there anything that needs to be done to let the driver run on newer kernel? in applesmc.c I see nothing about "regulator" being mentioned, is that whole thing gone?
