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 <lkp@intel.com> Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
