| Subject: misc: cxl: Fix possible null pointer dereference |
| |
| 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. |
