Armbian is a community driven open source project. Do you like to contribute your code?

had build, and now boot from os, dmesg |grep fbtft, display :

root@nanopineo:/etc/lirc# dmesg|grep fbtft
[   10.705494] fbtft: module is from the staging directory, the quality is unknown, you have been warned.
[   10.712490] fbtft_device: module is from the staging directory, the quality is unknown, you have been warned.
[   10.714226] fbtft_device: spi_busnum_to_master(0) returned NULL
[   10.714235] fbtft_device: failed to register SPI device

my patch is build from: https://github.com/prius0304/fbtft---SSD1322/blob/master/fb_ssd1322.c
