Subject: [PATCH 03/30] habanalabs: fix possible memory leak in MMU DR fini
Date: Sat, 22 Jan 2022 21:57:04 +0200 [thread overview]
Message-ID: <20220122195731.934494-3-ogabbay@kernel.org> (raw)
In-Reply-To: <20220122195731.934494-1-ogabbay@kernel.org>
From: Ohad Sharabi <osharabi@habana.ai>
This patch fixes what seems to be copy paste error.
We will have a memory leak if the host-resident shadow is NULL (which
will likely happen as the DR and HR are not dependent).
