What normally happens is that whatever registers the device will when registering the device supply platform data that the device later picks up from the struct device during probe. What you're saying is that the idea here is that driver unconditionally declares platform data and then other code scribbles over that before the driver instantiates. This is cleaner in that it keeps the platform configuration together and safer since the device can't exist before it's configuration is provided. > So we have the code doing the quirks determining the regulator_init_data > and passing this through platform_data, which AFAICT is exactly what > you want? No. There should be no sign of the platform data getting allocated or initialised in the driver consuming the platform data. It should purely be reading the data it gets passed by the platform initialisation code. Please make the use of platform data look like normal platform data use rather than going and inventing some new scheme.
