[PATCH 4.14 113/122] misc: cxl: Fix possible null pointer dereference

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: zhong jiang <zhongjiang@xxxxxxxxxx>

[ 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.
