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