Subject: [PATCH 5/8] scripts: get_abi.pl: ignore some sysfs nodes earlier
Date:   Thu, 23 Sep 2021 17:41:16 +0200
Message-Id: <5228789cbef8241d44504ad29fca5cab356cdc53.1632411447.git.mchehab+huawei@kernel.org>
In-Reply-To: <cover.1632411447.git.mchehab+huawei@kernel.org>

Precedence: bulk

When checking for undefined symbols, some nodes aren't easy
or don't make sense to be checked right now. Prevent allocating
memory for those, as they'll be ignored anyway.
