[dpdk-stable] [PATCH v4 1/2] lib/cmdline: release cl when cmdline exit

[zhihongx.peng@intel.com]

From: Zhihong Peng <zhihongx.peng@intel.com>

Malloc cl in the cmdline_stdin_new function, so release in the
cmdline_stdin_exit function is logical, so that cl will not be
released alone.

Fixes: af75078fece3 ("first public release")
