Thank you so much for the review comments, will update.

I would still leave 1 and 2 with corresponding names for sake of documentation.
Ok, will add for the sake of documentation.

Redundant assignment.
Noted, will update.

And here missed to address one of my comments.
Yes, will update.

Group it with other assignment(s), i.e. dev = ... above.
struct device *dev = ...;
struct device_node *np = ...;
agree, will update.
