Calling kzalloc() and related functions requires the

kzalloc(sizeof(struct dcn10_ipp), GFP_KERNEL);
A lot of other headers also miss a direct include in this file,
but this is the only one that causes a problem for now.

What version of the kernel are you building?
We have:
#include <linux/slab.h>
in os_types.h which gets included as part of this file:
#include <dc.h> -> #include <dc_types.h> -> #include <os_types.h>
