There is an alternative solution to fixing the imply keyword: Make the drivers use it properly by *actually* conditionally enabling the feature only when IS_REACHABLE, i.e. fix ice so that it uses IS_REACHABLE instead of IS_ENABLED, and so that its stub implementation in ice_ptp.h actually just silently does nothing but returns 0 to tell the rest of the driver things are fine.
I would consider IS_REACHABLE() part of the problem, not the solution, it makes
things magically build, but then surprises users at runtime when they do not get
the intended behavior.
