[ Upstream commit 7c35e699c88bd60734277b26962783c60e04b494 ]
If a device already has devres items attached before probing, a warning
backtrace is printed. However, this backtrace does not reveal the
offending device, leaving the user uninformed. Furthermore, using
WARN_ON() causes systems with panic-on-warn to reboot.
Fix this by replacing the WARN_ON() by a dev_crit() message.
Abort probing the device, to prevent doing more damage to the device's
resources.
