* crypto: arm64 - convert to use crypto_simd_usable()Eric Biggers2019-03-221-2/+3
| | | | | | | | | Replace all calls to may_use_simd() in the arm64 crypto code with crypto_simd_usable(), in order to allow testing the no-SIMD code paths.

* crypto: shash - remove useless setting of type flagsEric Biggers2018-07-091-4/+0
| | | | | | | | | | | | | | | Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this is redundant with the C structure type ('struct shash_alg'), and crypto_register_shash() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the shash algorithms. This patch shouldn't change any actual behavior.
