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.
