From 7f8da9915fcc6386edf86471bf31e162845930a4 Mon Sep 17 00:00:00 2001 From: Eric Snowberg Date: Thu, 2 Mar 2023 11:46:47 -0500 Subject: KEYS: Create static version of public_key_verify_signature The kernel test robot reports undefined reference to public_key_verify_signature when CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE is not defined. Create a static version in this case and return -EINVAL.
