Enable WPP Event Tracing for both the WSK library and the test driver
The WPP Event Tracing can be disabled which means return to the good old DbgPrintEx routine. To disable WPP, the following steps need to be done: - commenting the line `#define EVENT_TRACING` in project's trace.h file, - setting the "Run Wpp Tracing" option in project settings to No. Signed-off-by: Martin Drab <[email protected]>
