From b000700d6db50c933ce8b661154e26cf4ad06dba Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Sat, 26 Dec 2020 15:27:14 +0800 Subject: [PATCH] habanalabs: Fix memleak in hl_device_reset When kzalloc() fails, we should execute hl_mmu_fini() to release the MMU module. It's the same when hl_ctx_init() fails.
