Subject: [PATCH 04/13] RISC-V: KVM: Drop the return value of kvm_riscv_vcpu_aia_init()
Date: Thu,  5 Jun 2025 11:44:49 +0530	[thread overview]
Message-ID: <20250605061458.196003-5-apatel@ventanamicro.com> (raw)
In-Reply-To: <20250605061458.196003-1-apatel@ventanamicro.com>

The kvm_riscv_vcpu_aia_init() does not return any failure so drop
the return value which is always zero.
