The structure pointer passed to container_of() is never NULL; that was already checked. That means that the result of container_of() operations on it is also never NULL, even though se_node_acl is the first element of the structure embedding it. On top of that, it is misleading to perform a NULL check on the result of container_of() because the position of the contained element could change, which would make the test invalid. Remove the unnecessary NULL check. As it turns out, the container_of operation was only made for the purpose of the NULL check. If the container_of is actually needed, it is repeated later. Remove the container_of operation as well. The NULL check was identified and removed with the following Coccinelle script. @@ type t; identifier v; statement s; @@ <+... ( t v = container_of(...); | v = container_of(...); ) ... when != v - if (\( !v \| v == NULL \) ) s ...+> Link: https://lore.kernel.org/r/20210510040817.2050266-1-linux@roeck-us.net Cc: "Martin K.
