I admit it is probably a seperate change...

... motivated by this "if (!timeout) dev_err("timeout!")" which is super
confusing to read because the logic is paradox.

Agreed. Another seperate change. A timeout is not something the user
need to be aware of. It can regularly happen while an EEPROM is erasing
a page. The client driver will probably handle it correctly by trying
again. Only if the client driver sees a problem, then the user should be
notified. But not in the controller driver.
