From a16a17d3eaa4866c65366150fca48537de3a924c Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Tue, 10 Sep 2024 16:30:20 +0200 Subject: crypto: drivers - Drop sign/verify operations The drivers aspeed-acry.c, hpre_crypto.c and jh7110-rsa.c purport to implement sign/verify operations for raw (unpadded) "rsa". But there is no such thing as message digests generally need to be padded according to a predefined scheme (such as PSS or PKCS#1) to match the size of the usually much larger RSA keys. The bogus sign/verify operations defined by these drivers are never called but block removal of sign/verify from akcipher_alg. Drop them.
