Hi CK,

Thanks for the reminder.
 * It was intended to apply the new declaration style (ref: 
   https://patchwork.kernel.org/project/linux-mediatek/patch/20220311015506.11232-9-nancy.lin@mediatek.com/
   ), but it seems redundant. I should add the new settings in the
   original way first, then keep the definition changes in the
   subsequence patch.

Thanks,
Moudy
