Totally agreed with what you are saying here but I don't really think
using the flag is a workaround. It is just a way to ensure no
regressions occurred until all drivers are adapted and also having all
of them enabled is the behaviour. For me adapt the rest of driver code
should be a different patch set after this driver is properly
finished and mainlined.
