There is no point having these complaints to be dev_err as
they are just adding noise to bootlog.

No, errors are errors and not displaying them just makes it harder for
people to debug things. If you don't want to see errors just change
your system configuratiion to hide them. If you don't like deferred
probing please contribute to the efforts to order probing.
Please use subject lines matching the style for the subsystem. This
makes it easier for people to identify relevant patches.

For sure I want to see all errors, but this is not hardware error nor
kernel misconfiguration, so showing it to the user is a bit pointless.
I'm using quiet boot on production systems and technicians are told
to report all errors they see... This one pops up and has nothing
to do with errorneous behaviour.

I just tried to make it consistend to other subsystems where patches to
silence deferred probing warnings are accepted...

I wasn't aware of it, sorry. Will fix it next time.
Best regards,

How do we know that it's not a kernel misconfiguration? It's common for
people to not build some of the component drivers they need.

Which subsystems are these? We should look at fixing them...

Is what you described really a misconfiguration? Enabling debug when
something does not work seems obvious thing to do, but okay, perhaps
anything bellow error level would make me happy enough.

As a side note, which efforts are you reffering to here?

tty and usb for example. I do not consider wise to looking at them until
this very subsystem gets fixed first to not distract ourselves ;-)
(Also I have admit, that accepted patches hide error message on deferred
probe only, but above occurs _also_ on deferred probe and yes, it would be
nice to have that fixed)
Best regards,

Yes, it's something that's really common when people configure their own
kernels.

Things like Raphael's device dependencies work.

This really does make it harder to figure out what's going on when the
dependency is actually missing - it transforms things into a silent
failure.
