Subject: [dpdk-dev] [PATCH 2/6] net/ice/base: fix resource leak
Date: Tue, 23 Jul 2019 11:51:11 +0800	[thread overview]
Message-ID: <20190723035115.42664-3-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20190723035115.42664-1-qi.z.zhang@intel.com>

We don't free s_rule if ice_aq_sw_rules() returns a non-zero status. If
it returned a zero status, s_rule would be freed right after, so this
implies it should be freed within the scope of the function regardless.

Fixes: c7dd15931183 ("net/ice/base: add virtual switch code")
