Having a local variable of 1024 bytes on 64-bit architectures is a bit too much, and I ran into this warning while trying to see what functions use the largest stack: drivers/staging/fbtft/fbtft-sysfs.c: In function 'store_gamma_curve': drivers/staging/fbtft/fbtft-sysfs.c:132:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=] As there is no need for 64-bit gamma values (on 32-bit architectures, we don't use those either), I'm changing the type from 'unsigned long' to 'u32' here, which cuts the required space in half everywhere.

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 See wiki for more information: https://github.com/notro/fbtft/wiki Source: https://github.com/notro/fbtft/
