Subject: [dpdk-dev] [PATCH] regex/mlx5: fix RegEx probing error flow
Date: Tue, 31 Aug 2021 23:38:38 +0300 [thread overview]
Message-ID: <20210831203838.3411249-1-michaelba@nvidia.com> (raw)
In RegEx device probing, there is register read trying after context
device creation.
When the reading fails, the context device was not freed what caused a
memory leak.
Free it.
Fixes: f324162e8e77 ("regex/mlx5: support combined rule file")
