Jan Sebastian Götte 92e3e88488 Staging: fbtft: Fix GPIO handling
Commit c440eee1a7 ("Staging: fbtft: Switch to the gpio descriptor
interface") breaks GPIO handling. In several places, checks to only set
a GPIO if it was configured ended up backwards.
I have tested this fix. The fixed driver works with a ili9486
display connected to a raspberry pi via SPI.

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
