The error handling in fbtft_framebuffer_alloc() mixes managed allocation and plain allocation, and performs error handling in an order different from the order in fbtft_framebuffer_release(). Fix them by moving vmem allocation closer to where it is used, and using plain kzalloc() for txbuf allocation. Also remove the duplicate call to fb_deferred_io_cleanup().

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
