            Bug ID: 195330
           Summary: Reduce gpioctl output
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: jumpnowtek at gmail.com

gpioctl enumerates non-switch cmdline args to stdout when
doing simple reads or writes.

root at duovero:~ # gpioctl 110
0/110
0
root at duovero:~ # gpioctl 110 1
0/110
1/1
root at duovero:~ # gpioctl 110
0/110
1

It's confusing and not documented.

I'm suggesting removing those lines so the output looks like

root at duovero:~ # gpioctl 110
1
root at duovero:~ # gpioctl 110 0
root at duovero:~ # gpioctl 110
0

        if (ctlfile == NULL)
                ctlfile = defctlfile;
