When converting to device property API the commit8b2d3aeeb7("fbtft: Make use of device property API") mistakenly placed the reading of the first value inside the loop, that jumps over value after initialization sequence or sleep commands. Move the above mentioned reading outside of the loop to restore correct behaviour. Besides that, we are using pre-increment operation which may lead to out of the boundary access at the end of sequence. Thus, allocate buffer with an additional element at the end to prevent out of the boundary access.

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
