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.
