Maybe do not use the out of tree version, use the kernel mainline one
(drivers/staging/fbtft) as stated here [1]:
2015-01-19
The FBTFT drivers are now in the Linux kernel staging tree:
https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/tree/drivers/staging/fbtft?h=staging-testing
Development in this github repo has ceased.
