From eb85eec858c1a5c11d3a0bff403f6440b05b40dc Mon Sep 17 00:00:00 2001 From: Ohad Sharabi Date: Mon, 3 Jan 2022 09:48:27 +0200 Subject: [PATCH] habanalabs: fix possible memory leak in MMU DR fini 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).
