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.

Fixes: db6c43bd2132 ("crypto: KEYS: convert public key and digsig asym to the akcipher api")
Reported-by: kernel test robot <lkp@intel.com>

Back in September of 2021, I received the following message from the test robot [1].  
Within the message it asks that I add the Reported-by tag.  To prevent the test robot 
from generating this error again,  I have included this patch at the beginning of the 
series for the last year and a half.  It would be great if someone would apply the first 
two patches.
