Subject: [PATCH 1/4] riscv: kvm: vcpu_timer: fix unused variable warnings
Date: Sun, 14 Aug 2022 15:12:35 +0100	[thread overview]
Message-ID: <20220814141237.493457-2-mail@conchuod.ie> (raw)
In-Reply-To: <20220814141237.493457-1-mail@conchuod.ie>

From: Conor Dooley <conor.dooley@microchip.com>

In two places, csr is set but never used:

arch/riscv/kvm/vcpu_timer.c:302:23: warning: variable 'csr' set but not used [-Wunused-but-set-variable]
        struct kvm_vcpu_csr *csr;
                             ^
arch/riscv/kvm/vcpu_timer.c:327:23: warning: variable 'csr' set but not used [-Wunused-but-set-variable]
        struct kvm_vcpu_csr *csr;
                             ^

Remove the variable.
