[PATCH v6 4/8] crypto: ccp: Fix uapi definitions of PSP errors

[PATCH v6 4/8] crypto: ccp: Fix uapi definitions of PSP errors
Posted by Dionna Glaze 1 year, 2 months ago 
From: Alexey Kardashevskiy <aik@amd.com>

Additions to the error enum after the explicit 0x27 setting for
SEV_RET_INVALID_KEY leads to incorrect value assignments.

Use explicit values to match the manufacturer specifications more
clearly.

Fixes: 3a45dc2b419e ("crypto: ccp: Define the SEV-SNP commands")

@Boris or @Herbert, can we pick up this fix separate from this series?
It can probably go through either the tip tree or crypto tree.

This usually goes through the crypto tree. Unless Herbert really wants me to
pick it up...
