From: Michał Mirosław <mirq-linux@xxxxxxxxxxxx>
commit 693a8e936590f93451e6f5a3d748616f5a59c80b upstream.
dev_err_probe() prepends the message with an error code. Let's make it
more readable by translating the code to a more recognisable symbol.
Fixes: a787e5400a1c ("driver core: add device probe log helper")
