Subject: [PATCH v2 03/11] RISC-V: KVM: Return correct code for hsm stop function
Date: Thu, 15 Dec 2022 09:00:38 -0800 [thread overview]
Message-ID: <20221215170046.2010255-4-atishp@rivosinc.com> (raw)
In-Reply-To: <20221215170046.2010255-1-atishp@rivosinc.com>
According to the SBI specification, the stop function can only
return error code SBI_ERR_FAILED. However, currently it returns
-EINVAL which will be mapped SBI_ERR_INVALID_PARAM.
Return the appropriate linux error code.
