> The msm_dp_utils_pack_sdp_header() accepts an unlimited-size u32 pointer
> for the header output, while it expects a two-element array. It performs
> a sizeof check which is always true on 64-bit platforms (since
> sizeof(u32*) is 8) and is always falce on 32-bit platforms. It returns
> an error code which nobody actually checks.
>
> Fix the function interface to accept u32[2] and return void, skipping
> all the checks.
