Subject: [dpdk-dev] [PATCH] ethdev: avoid unregistering a non-allocated callback
Date: Tue, 13 Jul 2021 15:17:13 +0200
Message-ID: <20210713131714.964500-1-thomas@monjalon.net> (raw)

When registering a new event callback, if allocation fails,
there is no need for unregistering the callback,
because it is not registered.

Fixes: 9ec0b3869d8d ("ethdev: allow event registration for all ports")
Cc: stable@dpdk.org
