Subject: [PATCH] habanalabs: fix possible memory leak in MMU DR fini
Git-commit: eb85eec858c1a5c11d3a0bff403f6440b05b40dc
Patch-mainline: v5.18-rc1
References: git-fixes
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).
