When compiling with Clang, the following warning is observed:

  CC       tools/objtool/arch/x86/decode.o
arch/x86/decode.c:141:20: error: implicit conversion from enumeration
type 'enum op_src_type' to different enumeration
type 'enum op_dest_type' [-Werror,-Wenum-conversion]

  op->dest.type = OP_SRC_REG;
                ~ ^~~~~~~~~~
