[PATCH v3 0/2] tpm: Attempt to return value not in enum

[Andrew Goodbody]

The function tpm2_name_to_algorithm attempts to return -EINVAL
for an error but that is not included in the enum tpm2_algorithms
which is defined as the return type for this function.
Add -EINVAL as TPM2_ALG_INVAL to the enum so that it can be
returned as desired. Update the code to use this enum value.
