[PATCH] cxl: Delete an unnecessary check before the function call "kfree"

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

The kfree() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
