Subject: [PATCH 4.19 26/41] kgdboc: Fix warning with module build
Date: Thu, 6 Dec 2018 15:39:06 +0100 [thread overview]
Message-ID: <20181206142952.013741780@linuxfoundation.org> (raw)
In-Reply-To: <20181206142949.757402551@linuxfoundation.org>
4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laura Abbott <labbott@redhat.com>
commit 1cd25cbb2fedbc777f3a8c3cb1ba69b645aeaa64 upstream.
After 2dd453168643 ("kgdboc: Fix restrict error"), kgdboc_option_setup is
now only used when built in, resulting in a warning when compiled as a
module:
drivers/tty/serial/kgdboc.c:134:12: warning: 'kgdboc_option_setup' defined but not used [-Wunused-function]
static int kgdboc_option_setup(char *opt)
^~~~~~~~~~~~~~~~~~~
Move the function under the appropriate ifdef for builtin only.
Fixes: 2dd453168643 ("kgdboc: Fix restrict error")
