Ulf reported an issue[1] with fw_devlink. This series tries to fix that issue. I replicated a similar set up on my end and I confirmed: - A simple-bus only device is probed. - Another device listing simple-bus as a 2nd compatible string isn't probed. Ulf, mind testing this? v1->v2: - Switched to probing the simple-bus device instead of marking it as NEVER_PROBES. v2->v3: - Moved all the code into the simple-pm-bus driver - Addressed Ulf's comment about the remove() code missing a check.
