Subject: fix tapenabler return code
X-Git-Tag: v0.6.0-rc1~635
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=194e3c5bc5e0fbb7d41cfcbe913c4264782cdd5b;p=openocd

fix tapenabler return code

if tap enable/disable failed then a warning was written to the log, but JIM_OK was returned. if using openocd via a TCP interface to the TCL port, there is no way to catch that the command failed (it didn't enable the tap, so it failed)
now it return an error if it fails.
