while that patch prevents the error message generation, it still
doesn't cause the code to be processed correctly ... if you take a
look at the generated kernal-api.html file, in the section on "CRC
Functions", the page for that source file is still empty.
so your patch will recognize the regular expressions, but it's clear
more of the script needs to be fixed to then *generate* the proper
output.
