If anyone has any objections, please let me know. ------------------ From: Srish Srinivasan [ Upstream commit 0d0eafedcaf4939819d38ede6ad355ea37acd978 ] PLPKS variables with the PLPKS_WRAPPINGKEY policy bit set are not readable. Return -EPERM instead of -EINVAL in this case to better reflect the access restriction being enforced.
