Subject: [PATCH 01/23] interconnect: fix mem leak when freeing nodes
Date: Wed,  1 Feb 2023 11:15:37 +0100	[thread overview]
Message-ID: <20230201101559.15529-2-johan+linaro@kernel.org> (raw)
In-Reply-To: <20230201101559.15529-1-johan+linaro@kernel.org>

The node link array is allocated when adding links to a node but is not
deallocated when nodes are destroyed.

Fixes: 11f1ceca7031 ("interconnect: Add generic on-chip interconnect API")
Cc: stable@vger.kernel.org      # 5.1
