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. 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. v3->v4: - Added support for driver_override to accommodate the case where new transparent bus compatible strings are added to DT, but the kernel hasn't been updated yet. - Added/updated comments to give more details. - Adding Ulf's Tested-by that he have for v3 (v4 didn't change by much).
