Subject: [PATCH 7/9] extrawarn: do not disable -Wmain at W=1 level
Date: Fri, 11 Aug 2023 16:03:25 +0200 [thread overview]
Message-ID: <20230811140327.3754597-8-arnd@kernel.org> (raw)
In-Reply-To: <20230811140327.3754597-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
There is only one function in architecture independent code that has
a local variable named main(), and it seems fine to warn about this
at the W=1 level, so move it there to declutter the normal command
line slightly.
