Subject: [PATCH 03/13] RISC-V: KVM: Check kvm_riscv_vcpu_alloc_vector_context() return value
Date: Thu, 5 Jun 2025 11:44:48 +0530 [thread overview]
Message-ID: <20250605061458.196003-4-apatel@ventanamicro.com> (raw)
In-Reply-To: <20250605061458.196003-1-apatel@ventanamicro.com>
The kvm_riscv_vcpu_alloc_vector_context() does return an error code
upon failure so don't ignore this in kvm_arch_vcpu_create().
