[igt-dev] [PATCH v3 08/12] scripts/code_cov_parse_info: better handle test name

[Mauro Carvalho Chehab]

From: Mauro Carvalho Chehab <mchehab at kernel.org>

The TN field generated by standard lcov is weird: it keeps
repeating the TN field from time to time. At genhtml, it seems
that only the first one is used.

As we're using TN to indicate the test name, preserve all different
test names at the output file.

Also, printing such names doesn't really makes sense when
--print-used and --print-unused command line options are used,
and printing a list of 100+ names won't make much sense.

So, just remove printing the test names.
