That should be <linux/io.h>, actually.

Sorry, I made the driver look for product name "AMILO A1655" but that is
actually the board name.  Could you try changing DMI_PRODUCT_NAME to
DMI_BOARD_NAME?

This is the rfkill device exposed by the regular wireless driver.  Since
it doesn't know anything about the model-specific blocking behaviour, it
appears to treat it as hard-blocking.  But that shouldn't matter if we
can get this new driver working.
