Default [Q] Help in compiling kernel

I'm currently compiling my kernel with bricked msm_thermal.

Currently I'm stuck at this compiler warning.

Compiled again and stuck to a different problem

drivers/built-in.o: In function `check_temp':
:(.text+0x202e90): undefined reference to `msm_mpdec_cpudata'
:(.text+0x202e94): undefined reference to `msm_mpdec_cpudata'
msm_thermal.c which has funchion check_temp, there is already an #include to msm_mpdecision.h which holds the msm_mpdec_cpudata

Any help will be appreciated
