From 824db5cd1ec9b95c254fc317c3999f6b53e98b12 Mon Sep 17 00:00:00 2001 From: Tianjia Zhang Date: Thu, 10 Nov 2022 18:42:04 +0800 Subject: crypto: arm64 - Fix unused variable compilation warnings of cpu_feature The cpu feature defined by MODULE_DEVICE_TABLE is only referenced when compiling as a module, and the warning of unused variable will be encountered when compiling with intree. The warning can be removed by adding the __maybe_unused flag. Fixes: 03c9a333fef1 ("crypto: arm64/ghash - add NEON accelerated fallback for 64-bit PMULL") Fixes: ae1b83c7d572 ("crypto: arm64/sm4 - add CE implementation for GCM mode") Reported-by: kernel test robot Signed-off-by: Tianjia Zhang Signed-off-by: Herbert Xu --- arch/arm64/crypto/ghash-ce-glue.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm64/crypto/ghash-ce-glue.c') diff --git a/arch/arm64/crypto/ghash-ce-glue.c b/arch/arm64/crypto/ghash-ce-glue.c index 15794fe21a0b..e5e9adc1fcf4 100644 --- a/arch/arm64/crypto/ghash-ce-glue.c +++ b/arch/arm64/crypto/ghash-ce-glue.c @@ -508,7 +508,7 @@ static void __exit ghash_ce_mod_exit(void) crypto_unregister_shash(&ghash_alg); } -static const struct cpu_feature ghash_cpu_feature[] = { +static const struct cpu_feature __maybe_unused ghash_cpu_feature[] = { { cpu_feature(PMULL) }, { } }; MODULE_DEVICE_TABLE(cpu, ghash_cpu_feature); -- cgit
