Viresh Kumar b758d68618 greybus: connection: bind protocol after the connection is operational ... We may bind protocol with a connection from gb_connection_create(), if bundle's device_id is already set. That's not the case until now. But if the protocol is initialized with a call to protocol->connection_init() from this place, kernel will crash. This will happen because the connection isn't fully initialized yet, for example its operation list isn't initialized yet. And as soon as the protocol driver tries to send a request to the module from its connection_init() callback, we will add an operation to this uninitialized list. And it will crash while doing: prev->next = new; Try to bind the connection with a protocol only after the connection is ready for operations.
