[dpdk-dev] [PATCH] ethdev: avoid unregistering a non-allocated callback

[Thomas Monjalon]

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")
