mainline inclusion from mainline-v6.4-rc1 commit 7f8da9915fcc6386edf86471bf31e162845930a4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9SY02
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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.
