From a044ef71043ebc23903f657fd51b10783d34918b Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Thu, 3 Aug 2023 13:32:54 -0300 Subject: [PATCH] RISC-V: KVM: use ENOENT in *_one_reg() when extension is unavailable Following a similar logic as the previous patch let's minimize the EINVAL usage in *_one_reg() APIs by using ENOENT when an extension that implements the reg is not available. For consistency we're also replacing an EOPNOTSUPP instance that should be an ENOENT since it's an "extension is not available" error.
