These were all bogus, since the actual problem here is the incorrect use of of_ptr(). Since the driver (like any other modern platform driver) only works in combination with CONFIG_OF, there is no point in hiding the reference, so just remove that along with all the pointless #ifdef checks in the driver. This improves build coverage and avoids running into the same problem again when another part of the driver gets changed that relies on the #ifdef blocks to be completely matched.
