[Q] kernel rk2918 help to compile

Hello
My tablet is a TITAN 7010B.
RK2918
Like many other brands, Titan has not released the GPL. No respect to Android and its users.

Based on https://github.com/joaquimorg/androi...ockchip_rk2918

I tried doing a kernel for my tablet.
I added the source code of the touchscreen and the sound chip.

The compilation stops near the end of the following error that is not how to solve


sound/built-in.o: In function `codec_set_spk':
last.c:(.text+0x1ba28): multiple definition of `codec_set_spk'
arch/arm/mach-rk29/built-in.o:board-rk29yf-power.c:(.text+0xb470): first defined here
make: *** [vmlinux.o] Error 1
