A couple of ad-hoc cleanups. No functional changes intended.

v3:
- rebased on top of driver-core-testing (Philipp)
- added tags (Philipp)

v2:
- fixed plural vs. singular "to have" (Philipp)

Andy Shevchenko (2):
  devres: Switch to use dev_err_probe() for unification
  devres: Don't use "proxy" headers

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.

principle.
