A pointer means that it is allocated and deallocated by somebody. 
Probably you meant that it is a pointer into the dpu_hw_pipe member 
(with dpu_hw_pipe having sw_pipe's for rect0 and rect1).

I thought about this. And ended up with the dpu_sw_pipe having a 
dpu_hw_pipe pointer inside, but itself being a member of plane state. 
This way the plane state contains such data as multirect mode and rectangle.
