Segmentation fault

Hi,

In the cleanupHook the pointers are deleted but the vector is not cleared.
This will result in seg fault in case you

• configure and start the component
• stop and cleanup
• configure again

For this to be solved a m_drivers.clear(); is necessary in cleanupHook. I have done these changes and documented the code a bit more. Will do a pull request once this issue and the one I opened earlier are further tested.
