Subject: [PATCH v6 17/20] modpost: merge bad_tosec=ALL_EXIT_SECTIONS entries in sectioncheck table
Date: Mon, 22 May 2023 01:04:22 +0900	[thread overview]
Message-ID: <20230521160426.1881124-18-masahiroy@kernel.org> (raw)
In-Reply-To: <20230521160426.1881124-1-masahiroy@kernel.org>

There is no distinction between TEXT_TO_ANY_EXIT and DATA_TO_ANY_EXIT.
Just merge them.
