devres: switch to use dev_err_probe() for unification
Patch series "devres: A couple of cleanups". A couple of ad-hoc cleanups. No functional changes intended. This patch (of 2): The devm_*() APIs are supposed to be called during the ->probe() stage. Many drivers (especially new ones) have switched to use dev_err_probe() for error messaging for the sake of unification. Let's do the same in the devres APIs.
