Deletion of checks before specific function calls in Linux source files

Edit Package Deletion_of_checks_before_specific_function_calls_in_Linux_source_files

A couple of functions performs input parameter validation before their implementations will try further actions with side effects. Some calling functions perform similar safety checks.

Functions which release a system resource are occasionally documented in the way that they tolerate the passing of a null pointer for example.
There is mostly no need because of this fact that a function caller repeats a corresponding check.

Semantic patch patterns can help to identify update candidates also in Linux source files.
