Subject[PATCH AUTOSEL 4.14 106/115] misc: cxl: Fix possible null pointer dereference
Date
From: zhong jiang <zhongjiang@huawei.com>

[ Upstream commit 3dac3583bf1a61db6aaf31dfd752c677a4400afd ]

It is not safe to dereference an object before a null test. It is
not needed and just remove them. Ftrace can be used instead.
