Colin Ian King 5817eca067 staging: fbtft: make several arrays static const, makes object smaller 
Don't populate the arrays on the stack but instead make them
static const. Makes the object code smaller by 1329 bytes.

README 

  FBTFT
=========

Linux Framebuffer drivers for small TFT LCD display modules.
The module 'fbtft' makes writing drivers for some of these displays very easy.

Development is done on a Raspberry Pi running the Raspbian "wheezy" distribution.

INSTALLATION
  Download kernel sources

  From Linux 3.15
    cd drivers/video/fbdev/fbtft
    git clone https://github.com/notro/fbtft.git

    Add to drivers/video/fbdev/Kconfig:   source "drivers/video/fbdev/fbtft/Kconfig"
    Add to drivers/video/fbdev/Makefile:  obj-y += fbtft/

  Before Linux 3.15
    cd drivers/video
    git clone https://github.com/notro/fbtft.git

    Add to drivers/video/Kconfig:   source "drivers/video/fbtft/Kconfig"
    Add to drivers/video/Makefile:  obj-y += fbtft/

  Enable driver(s) in menuconfig and build the kernel
