Subject: [PATCH AUTOSEL 4.4 19/40] cpufeature: avoid warning when compiling with clang
Date: Sat, 9 Nov 2019 21:50:11 -0500 [thread overview]
Message-ID: <20191110025032.827-19-sashal@kernel.org> (raw)
In-Reply-To: <20191110025032.827-1-sashal@kernel.org>
From: Stefan Agner <stefan@agner.ch>
[ Upstream commit c785896b21dd8e156326ff660050b0074d3431df ]
The table id (second) argument to MODULE_DEVICE_TABLE is often
referenced otherwise. This is not the case for CPU features. This
leads to warnings when building the kernel with Clang:
arch/arm/crypto/aes-ce-glue.c:450:1: warning: variable
'cpu_feature_match_AES' is not needed and will not be emitted
[-Wunneeded-internal-declaration]
module_cpu_feature_match(AES, aes_init);
^
Avoid warnings by using __maybe_unused, similar to commit 1f318a8bafcf
("modules: mark __inittest/__exittest as __maybe_unused").
Fixes: 67bad2fdb754 ("cpu: add generic support for CPU feature based module autoloading")
