error: ‘target’ may be used uninitialized in arch/mips/net/ebpf_jit.c

[Matt Redfearn <matt.redfearn@xxxxxxxxxx>]

Hi David,

I see the following compiler error when I turn on CONFIG_MIPS_EBPF_JIT 
with v4.13 and v4.14-rc1 (cavium_octeon_defconfig based)

This is with gcc:

gcc version 4.9.2 (Codescape GNU Tools 2016.05-03 for MIPS MTI Linux)


arch/mips/net/ebpf_jit.c: In function ‘build_one_insn’:
arch/mips/net/ebpf_jit.c:1119:80: error: ‘target’ may be used 
uninitialized in this function [-Werror=maybe-uninitialized]
    emit_instr(ctx, j, target);
^
cc1: all warnings being treated as errors


This appears to have been the case since the ebpf_jit was merged in 
b6bd53f9c4e825fca82fe1392157c78443c814ab.

Thanks,

Matt
