objections, please let us know.
===============
[ Upstream commit 00420a65fa2beb3206090ead86942484df2275f3 ]
The has_key logic is wrong for shash algorithms as they always
have a setkey function. So we should instead be testing against
shash_no_setkey.
Fixes: a5596d633278 ("crypto: hash - Add crypto_ahash_has_setkey")
