Hi Jean

I added three lines, please refer to the codes below, Am I right?
static int
w83792d_detach_client(struct i2c_client *client)
{
int err;
struct w83792d_data *data = i2c_get_clientdata(client);
if ((err = i2c_detach_client(client))) {
.../* some codes omitted here! */
}
if (i2c_get_clientdata(client)==NULL) {
/* subclients */
i2c_detach_client(&(data->lm75[0])); <-- added!
i2c_detach_client(&(data->lm75[1])); <-- added!
kfree(data->lm75); <-- added!
kfree(client);
} else {
/* main client */
kfree(i2c_get_clientdata(client));
}
return 0;
}

I meet a problem when load the 792 module after the modification to
1*-5*:
W83792d 0-002f: Subclient 1 registration at address 0x48 failed.
The 792 modules does not work, does it have something to do with your
item 6*?
Do you know how to solve this problem?
Thanks
Best Regards
Chunhao
