(Lucas) v3 : Separate commit for lib. (Kamil) v4 : Refactor to use composition strategy for driver and device type filtering. Refactor code to improve memory allocation and error handling. (Lucas) v5 : Introduce device card match function to return collection of matching devices using device filter. v6 : Separate commit for device card match function. (Zbigniew) Function description modification for device card match function. (Zbigniew) v7 : Single return for card match function. (Krzysztof) v8 : Removed 'drivers' array as card match function parameter. (Zbigniew) v9 : Fixed allocation in card match instead of multiple realloc.
