2017-02-03staging: fbtft: change 'gamma' array to u32Arnd Bergmann
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.
