It's not a real problem. Any actual system using the driver will need to have explicit code which registers the I2C device for the WM8350, that code will need to set up the particular build for the board. The build time warning is there to try to make it a bit more obvious what's needed. Allowing the driver to be built without one of these defined provides build coverage which is helpful for subsystem maintainers. I might send a patch taking away the compile time warning, I'm not sure how likely it is that people will notice it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
