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
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/
