From: Nuno Sa <nuno.sa@xxxxxxxxxx>
Use dev_err_probe() in the probe() path. While at it, made some simple
improvements:
* Declare a struct device *dev helper. This also makes the style more
consistent (some places the helper was used and not in other places);
* Explicitly included the err.h and errno.h headers;
* Removed an useless else if();
* Removed some unnecessary line breaks.
