Subject: [PATCH 04/13] scripts: get_abi.pl: add an option to filter undefined results
Date: Thu, 23 Sep 2021 15:30:02 +0200 [thread overview]
Message-ID: <e0e4645b1647d2760efef2abd033c044d4c28424.1632402570.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1632402570.git.mchehab+huawei@kernel.org>
The output of this script can be too big. Add an option to
filter out results, in order to help finding issues at the
ABI files.
