Subject: [PATCH 02/27] modpost: do not write out any file when error occurred
Date: Mon, 25 Apr 2022 04:07:46 +0900 [thread overview]
Message-ID: <20220424190811.1678416-3-masahiroy@kernel.org> (raw)
In-Reply-To: <20220424190811.1678416-1-masahiroy@kernel.org>
If an error occurs, modpost will fail anyway. Do not write out
any content (, which might be invalid).
