[PATCH 13/17] scripts/code_cov_parse_info: warn if branch block is not zero

[Mauro Carvalho Chehab]

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

The lcov's info format has a field to be used for report branch
block. This is unused on json format (newer gcc), being always
zero. JSON doesn't contain it, so the parser doesn't support
it to be non-zero anymore. Print a warning if this happens.
