build issues

[jiriks74]

While building this kernel for the EvolutionX ceustom ROM I got into several issues:

../../../../../../kernel/xiaomi/mt6785/drivers/devfreq/helio-dvfsrc-v3/helio-dvfsrc-sysfs.c:254:23: error: variable 'dvfsrc' set but not used [-Werror,-Wunused-but-set-variable]                                
        struct helio_dvfsrc *dvfsrc;  
                             ^            
1 error generated.

make[2]: *** [/home/jirka/evo/kernel/xiaomi/mt6785/scripts/Makefile.build:637: drivers/devfreq] Error 2 

../../../../../../kernel/xiaomi/mt6785/drivers/input/touchscreen/mediatek/ft3418_i2c/focaltech_core.c:495:9: error: variable 'uppoint' set but not used [-Werror,-Wunused-but-set-variable]

make[6]: *** [/home/jirka/evo/kernel/xiaomi/mt6785/scripts/Makefile.build:333: drivers/input/touchscreen/mediatek/ft3418_i2c/focaltech_core.o] Error 1

These two I bodged by using an if statement but the one below is harder one to fix:

../../../../../../kernel/xiaomi/mt6785/drivers/misc/mediatek/base/power/mcdi/mtk_mcdi_governor.c:180:5: error: a function definition without a prototype is deprecated in all versions of C and is not supported 
in C2x [-Werror,-Wdeprecated-non-prototype]
int get_cluster_off_token(cpu) 

Would you please help me in building this? I've already built both EvolutionX's and LineageOS's kernel and they both have issues with trusty dereferencing a null pointer and therefore crashing the kernel before the boot even properly starts.

I'm building the rosemary-t-oss branch

The rosemary-t-oss2 branch fails too:
