Yeah, it is using a little bit tricky method.

From "logic" point of view, I think this patch has no bug,
but from "readable code" point of view,
I have no objection to exchange like above.

I'm not familiar with this driver,
so, can you handle it by incremental patch if you want?

Thank you for your help !!
Best regards
