Chenghao Duan e628b0524b riscv: bpf: Fix uninitialized symbol 'retval_off' [ Upstream commit `d0bf7cd5df` ] In the __arch_prepare_bpf_trampoline() function, retval_off is only meaningful when save_ret is true, so the current logic is correct. However, in the original logic, retval_off is only initialized under certain conditions; for example, in the fmod_ret logic, the compiler is not aware that the flags of the fmod_ret program (prog) have set BPF_TRAMP_F_CALL_ORIG, which results in an uninitialized symbol compilation warning. So initialize retval_off unconditionally to fix it.
