Subject: [PATCH v3 5/8] ml/cnxk: fix potential memory leak in xstats
Date: Thu, 16 Mar 2023 14:29:01 -0700 [thread overview]
Message-ID: <20230316212904.9318-6-syalavarthi@marvell.com> (raw)
In-Reply-To: <20230316212904.9318-1-syalavarthi@marvell.com>
Local buffer xstats_map is not released, when the xstats name
passed by the user application is not valid. This patch releases
the memory in such cases.
Fixes: 4ff4ab8e1a20 ("ml/cnxk: support extended statistics")
