Like that, you're never reaching the code below...

Anyway, at a first glance, it looked like you were sending the same commit twice,
but then I noticed... so... I would propose to change the commit title(s) to follow
this format:

media: mediatek: vcodec: enc: Set DMA mask only for MT8173 and MT8183

(but then, why mt8173/83 and not the others? this deserves an explanation...)
