if (found == false) {/* TODO: Park this device in Group 13 */dev_err(bus->dev, "Slave Entry not found");No break here? Otherwise...
Thats intentional. We want to still read next device that show up
}- } while (ret == 0);
... the outer loop may go endlessly. This condition doesn't look effective.
not really. We cant keep reading successfully. At some point all slaves will ignore and return ENODATA and we exit. Bus errors will also make it exit
BUT given that we have seen stuff i am inclined to add a counter, we cant have more than 11 device so that's a sane value to use :)
Yep. Keep in mind however that there could be theoretical corner cases: if a device is enumerated, loses sync and becomes attached again while you deal with others, you'd have more than 11 iterations.
