Subject: examples/power: fix json null termination
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8f8f876bd76f9ea996f0e80f32137aa9c2c2071a;p=dpdk.git

examples/power: fix json null termination

coverity complains about a null-termination after a read,
so we terminate once we exit the do-while read loop.

Coverity issue: 337680
Fixes: a63504a90f ("examples/power: add JSON string handling")
