For now I asked in the arm linux irc channel and got two people replying
(both added to Cc:):

Mark Brown (maintainer of SPI, regmap, ASoC and regulator) said:

1567019926 < broonie> ukleinek: I think that's a great idea and have
	thought about trying to implement it in the past.
1567019937 < broonie> ukleinek: Making the logs more directly readable
	is enormously helpful.

and Alexandre Belloni (arm/at91, mips/microsemi, rtc) said:

1567021451 < abelloni> ukleinek: seems good to me but it would probably
	be better to be able to generate the list

(I fully agree to the wish to generate the list, as I already wrote
before, I don't have a good idea how to do that without generating
C-Code by some means which is ugly and also complicated by the fact that
there are several locations (at least for now) that have definitions for
error codes.)

Best regards
Uwe
