tools: bpftool: remove duplicated error message on prog load
do_pin_fd() will already print out an error message if something goes wrong. Printing another error is unnecessary and will break JSON output, since error messages are full objects: $ bpftool -jp prog load tracex1_kern.o /sys/fs/bpf/a { "error": "can't pin the object (/sys/fs/bpf/a): File exists" },{ "error": "failed to pin program" } Fixes: 49a086c201a9 ("bpftool: implement prog load command") Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> Acked-by: Song Liu <songliubraving@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
