[PATCH v2 04/10] keys/trusted_keys: propagate wrapping key generation errors

[Srish Srinivasan]

plpks_gen_wrapping_key() returns a negative errno when default wrapping key
generation fails. However, trusted_pkwm_init() returns -EINVAL for all such
failures, discarding the original error.

Propagate the error returned by plpks_gen_wrapping_key() unchanged.
