Hi Geert

Using the macro is great, but it does seem a bit ugly having the
include in the middle of the file.

As far as i can see, phy.h only uses a pointer to a struct
phy_led_trigger, not struct phy_led_trigger itself. Could you try
removing the header file all together and just have a forward
declaration of phy_led_trigger?

Thanks
	Andrew
