Subject: [PATCH] examples/power: fix string null termination
After the read() the jason_data null termination is missing
for the case "indent < 0", for "indent > 0" and "indent == 0"
cases null termination is already handled.
So add the missing case "indent < 0" to the existing "indent == 0"
case to fix null termination.
Coverity issue: 337680
Fixes: a63504a90f ("examples/power: add JSON string handling")
