If it ever changes, the allocation part most likely would need an
update and since devm_add_action() takes this type of function, I
don't believe the argument would ever change from void * to something
else. With this it just adds an additional burden on the conversion.

Sure, but it makes a bit of inconsistency. Besides that dereferencing
of_node might also add a burden one day we want to get rid of it or
move it somewhere else, or convert to the list_head or so.
dev_of_node(dev) in this case prevents from looking into this case.
