    Subject[PATCH v3 0/3] Fixes for deferred_probe_timeout cleanup
    Date
    Just wanted to resubmit these three fixes for the
    deferred_probe_timeout cleanup that landed in the v5.7-rc1 merge
    window.

    The first resets the default timeout value back to zero so we
    have no behavioral change from 5.6. This avoids regressions on
    boards that have "optional links" in their device tree.

    The second changes the code to use dev_warn() instead of
    dev_WARN() to address complaints about unnecessary backtraces in
    the boot log.

    The last fixes an issue discovered by Yoshihiro Shimoda
    and Geert Uytterhoeven, where if a timeout was set, things
    like NFS root might fail due to wait_for_device_probe()
    not blocking until the timeout expires.

    thanks

    New in v3:
    * Just included the previously posted dev_warn() fix into the
    series, so they didn't collide.

    John Stultz (3):
    driver core: Revert default driver_deferred_probe_timeout value to 0
    driver core: Use dev_warn() instead of dev_WARN() for
    deferred_probe_timeout warnings
    driver core: Ensure wait_for_device_probe() waits until the
    deferred_probe_timeout fires
