| Subject: [PATCH] KVM: PPC: Remove set but not used variable 'ra', 'rs', 'rt' |
| |
| commit 4de0a8355463e068e443b48eb5ae32370155368b upstream. |
| |
| Fixes gcc '-Wunused-but-set-variable' warning: |
| |
| arch/powerpc/kvm/emulate_loadstore.c: In function kvmppc_emulate_loadstore: |
| arch/powerpc/kvm/emulate_loadstore.c:87:6: warning: variable ra set but not used [-Wunused-but-set-variable] |
| arch/powerpc/kvm/emulate_loadstore.c: In function kvmppc_emulate_loadstore: |
| arch/powerpc/kvm/emulate_loadstore.c:87:10: warning: variable rs set but not used [-Wunused-but-set-variable] |
| arch/powerpc/kvm/emulate_loadstore.c: In function kvmppc_emulate_loadstore: |
| arch/powerpc/kvm/emulate_loadstore.c:87:14: warning: variable rt set but not used [-Wunused-but-set-variable] |
| |
| They are not used since commit 2b33cb585f94 ("KVM: PPC: Reimplement |
| LOAD_FP/STORE_FP instruction mmio emulation with analyse_instr() input") |
