Okay, all good. The task in this mentorship is to make CodeChecker import 
the results from coccinelle into the UI.

Look at: 

If you can write a first simple report-converter for coccinelle and your 
prototype shows that you understand what needs to be done, we can devise a 
plan to make a full-fledged proper implementation with documentation, 
tests etc. If the plan is solid, I am happy to mentor you through these 
If your implementation works, the rough workflow should be:

make coccicheck > coccicheck_output
report-converter -o coccicheck_report -t coccinelle coccicheck_output
CodeChecker server &
CodeChecker store ./coccicheck_report -n linux

Then, we should see the coccinelle findings nicely presented in the UI.

Of course, it might be possible to modify coccinelle, provide parameters 
to the build target to simplify the parser to be implemented in 

If that is not clear, we go back one step in the introduction process of 
the task.
