Bug #149: Deletion of unnecessary checks before calls of the function "free"

Browse source 
The function "free" is documented in the way that no action shall occur for
a passed null pointer. It is therefore not needed that a function caller
repeats a corresponding check.

This issue was fixed by using the software Coccinelle 1.0.0-rc24.
