Staging: fbtft: add header for internal functions
Remove extern keyword from function prototypes to suppress warning from checkpatch.pl with --strict option: https://lkml.org/lkml/2013/7/23/422 fbtft maintainer Noralf Tronnes advised these functions are internal to this module & suggested moving these prototypes to new internal.h file. He also advised fbtft.h file will eventually live in include/linux/fbtft.h Suggested-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Drew Fustini <pdp7pdp7@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
