Matt Redfearn 94c3390ab8 MIPS: bpf: Fix uninitialised target compiler error ... Compiling ebpf_jit.c with gcc 4.9 results in a (likely spurious) compiler warning, as gcc has detected that the variable "target" may be used uninitialised. Since -Werror is active, this is treated as an error and causes a kernel build failure whenever CONFIG_MIPS_EBPF_JIT is enabled. arch/mips/net/ebpf_jit.c: In function 'build_one_insn': arch/mips/net/ebpf_jit.c:1118:80: error: 'target' may be used uninitialized in this function [-Werror=maybe-uninitialized] emit_instr(ctx, j, target); ^ cc1: all warnings being treated as errors Fix this by initialising "target" to 0. If it really is used uninitialised this would result in a jump to 0 and a detectable run time failure.
