This is where the declaration for struct device is along with other goodies like
get/put_device().

That is where struct file is declared.

This is where you get ida_simple_get() and ida_simple_remove() from.

This is where struct poll_table and poll_wait() comes from.

This gives you kzalloc() and kfree().

This gives you copy_from_user().

This gives you RPMSG_CREATE_EPT_IOCTL and RPMSG_DESTROY_EPT_IOCTL.

That one I agree with.
