Subject: [PATCH v2 1/4] scripts/get_feat.pl: allow output the parsed file names
Date:   Fri, 25 Mar 2022 15:05:11 +0100
Message-Id: <a924b46a80d750d808c28a27adffaa5d5a983e5c.1648216561.git.mchehab@kernel.org>

Such output could be helpful while debugging it, but its main
goal is to tell kernel_feat.py about what files were used
by the script. Thie way, kernel_feat.py can add those as
documentation dependencies.
