    Subject[PATCH 5.5 286/399] KVM: PPC: Remove set but not used variable ra, rs, rt
    Date
    From: zhengbin <zhengbin13@huawei.com>

    [ Upstream commit 4de0a8355463e068e443b48eb5ae32370155368b ]

    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")
