And this scenario happens because I wanted to avoid all that work preparing
trivial patch. In the other words, this thread could be few mails shorter
if anyone else took a chance ;-)

For sure, hassle with sending a patch and crediting everyone who contributed
properly is order of magnitude more time consuming than preparing patch itself.

So here's my last contribution to this painful thread. If you do not like it,
it's your turn :)

(and it'll be needed as Mark does not like patches being sended this way,
oh well, whoever sent original patch should first figure out why driver
outputs debug message just after warning one - so the simplest fix would
be just deleting that line)

Subject: [PATCH] ASoC: atmel_ssc_dai: Replace pr_debug with dev_dbg

Use dev_dbg for debug output, remove registration error message
as every user of atmel_ssc_set_audio prints its own error.
