Subject: Re: [PATCH 08/31] clk: mediatek: cpumux: Clean up included headers

> Some headers with the declaration of functions and structures aren't
> directly included. Explicitly include them so that future changes to
> other headers would not result in an unexpected build break.
> 
> On the header side, add forward declarations for any data structures
> whose pointers are used in function signatures. No headers are
> required.
