This error is getting thrown again because 'QCOM_DCC' is declared as 
tristate. Since DCC is using bootconfig apis which belongs to the __init 
section of the kernel, it can no longer be used as an external module to 
link with bootconfig apis. Will be changing it to bool in the next 
version. Thank you.
