It's a simple comparison and the result is even longer than the original. The *only* reason why this helper exists seems to be because it is getting used in *_find_device() callbacks. Honestly, I don't see a reason why this should be applied. And frankly, why bother making all these changes. It's a waste of time, in my opinion. Thierry

Initially for the purpose to be a callback it can be reused. The point is that it hides the dev_fwnode() machinery behind and taking into account ongoing discussion about constification of the dev_fwnode() we might need to touch this or similar places to avoid problems with compiler. > Honestly, I don't see a reason why this should be applied.

Maybe next time use that argument in the commit message. That's much more convincing than a useless "replace custom implementation" because that just makes it look like you're doing this to pass the time or something. Applied, with a slightly updated commit message, thanks. Thierry
