Uwe Kleine-König cb08d3d2a3 staging: fbtft: Make fbtft_remove_common() return void 
fbtft_remove_common() is only called with a non-NULL fb_info. (All
callers are in remove callbacks and the matching probe callbacks set
driver data accordingly.) So fbtft_remove_common() always returns zero.
Make it return void instead which makes it easier to see in the callers
that there is no error to handle.

Also the return value of platform and spi remove callbacks is ignored
anyway and not freeing resources in .remove() is a bad idea.

  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

    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
