Subject: [PATCH v3 17/24] powerpc/pseries: Log hcall return codes for PLPKS debug
From: Russell Currey <ruscur@...sell.cc>
The plpks code converts hypervisor return codes into their Linux
equivalents so that users can understand them. Having access to the
original return codes is really useful for debugging, so add a
pr_debug() so we don't lose information from the conversion.
