I was just looking at that lines in saa7164_i2c_register:
112 memcpy(&bus->i2c_algo, &saa7164_i2c_algo_template,
113 sizeof(bus->i2c_algo));
They seem like pointless to me. The real algo is set here:
93 static struct i2c_adapter saa7164_i2c_adap_template = {
94 .name = "saa7164",
95 .owner = THIS_MODULE,
96 .algo = &saa7164_i2c_algo_template,
97 };
This would also mean that this fields are also pointless:
254 struct i2c_algo_bit_data i2c_algo;
255 struct i2c_client i2c_client;
IMO, the issue pointed out by Dan would never appeared
if instead of using memcpy to fill the structures, it would just
get assigned; it's type safe, right?
Please correct me if I'm wrong,
Ezequiel.
