When core soft reset timeout happens, pullup doesn't check for the return value and proceeds setting up of event buffers and starts the controller. In this scneario, it is observed sometimes that the GEVTADDR LO/HI registers read zero while we are setting the run stop bit and we end up accessing address 0x00 leading to a crash. This series tries to address this issue by handling the timeout and return back appropriate error code to configfs for it to retry enumeration if it chooses to.
