We should at least be logging problems at debug level so there's something for people to go on without having to hack the kernel source.
But you can always do:
cat /sys/kernel/debug/devices_deferred
And you will find there deferred probe reason (thanks to patch 2/5).
Eventually if you want it in dmesg anyway, one can adjust probe_err function to log probe error on debug level as well.
