Blanket added the colon makes it messy when a string actually wants to
start with the prefix. The rule I've been using is lower case word when
the prefix was part of the string, upper case word when the prefix is
just being added as a prefix. I originally just had the prefix as raw
with no trailing space, so the individual print could decide to add a
colon, a space, or whatever as appropriate. But that just makes for
messy code with some files having every string look like ": Stuff
happened" and other files have every string look like " failed to ...".
The current version seems to be the most readable from the point of view
of writing the code and of reading the dmesg results.
And to be clear, the 'CT0' you have in your 'was' example only exists in
the internal tree. It never made it to upstream. It is also just plain
wrong. Each GT has two CTs - send and receive. So having 'CT1' meaning
some random CT on GT1 (as opposed to the read channel on GT0, for
example) was very confusing.
