As replied in 4/7, personally I prefer to use the "return 0/-1" if
there is no need to goto cleanup, it's more clear to let one
known what's the return value is, especially when the code
body of a function is long enough.
I will send v2 to add the patches to cleanup the macros not
used anymore in src/node_device_driver.h, and use the enum
in the utils.
Thanks for the reviewing.
