From 92e8d0323a5140c3e4a0e7098d3a5f43e2da87e8 Mon Sep 17 00:00:00 2001 From: Xianting Tian <xianting_tian@126.com> Date: Thu, 9 Jul 2020 11:06:07 -0400 Subject: [PATCH] scsi: virtio_scsi: Remove unnecessary condition check kmem_cache_destroy() and mempool_destroy() both correctly handle null pointer parameters. There is no need to check if the parameter is null before calling these functions.
