[PATCH] crypto: ccp: Fix uAPI definitions of PSP errors
From: Alexey Kardashevskiy <hidden>
Date: 2025-03-08 01:10:51
Also in:
linux-crypto, lkml, stable
Subsystem:
amd cryptographic coprocessor (ccp) driver - sev support, the rest · Maintainers:
Ashish Kalra, Tom Lendacky, Linus Torvalds
Additions to the error enum after 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")

I wrote it in the first place but since then it travelled a lot,
feel free to correct the chain of SOBs and RB :)
