Sachin Kamat b38b4b4f8c Input: keypad-omap - cleanup header file
Commit 2203747c97 ("ARM: omap: move platform_data definitions")
moved the file to the current location but forgot to remove the pointer
to its previous location. Clean it up. While at it also change the header
file protection macros appropriately.
