Subject: [PATCH v6 21/26] powerpc/pseries: Clarify warning when PLPKS password already set

From: Andrew Donnellan <[email-masked]>
Date: Fri, 10 Feb 2023 19:03:56 +1100

When the H_PKS_GEN_PASSWORD hcall returns H_IN_USE, operations that require
authentication (i.e. anything other than reading a world-readable variable)
will not work.

The current error message doesn't explain this clearly enough. Reword it
to emphasise that authenticated operations will fail.
