You need to return -ENOMEM. Are you talking about kmalloc or kzalloc ? Because for failing kmalloc -ENOMEM is returned as shown below: state = kmalloc(sizeof(struct s2250), GFP_KERNEL); if (state == NULL) { i2c_unregister_device(audio); return -ENOMEM; // ENOMEM is returned here. } Regards Santosh > > Regards > Oliver -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
