It took me a while to figure out a suggested layout for Linux
user-visible headers. I ended up with this:

  ./include/lcd/lcd.h -- includes #include <uapi/linux/lcd.h>
  ./include/uapi/linux/lcd.h -- this file will be installed to
      /usr/linux/lcd.h

Note on installing user-visible header files

 1) Add header-y += lcd.h line to include/uapi/linux/Kbuild

 2) Install sanitized header files into ./usr/include

    sudo make install_headers

 3) Copy ./usr/include to /usr/include

    sudo find usr/include \( -name .install -o -name ..install.cmd \) -delete
    sudo cp -rv usr/include/* /usr/include
