X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9b52ddeb468c74db7f652f7ac5a390591bb47dc7;p=linux.git

s390/pkey_pckmo: Return with success for valid protected key types

The key_to_protkey handler function in module pkey_pckmo should return
with success on all known protected key types, including the new types
introduced by fd197556eef5 ("s390/pkey: Add AES xts and HMAC clear key
token support").
