dev_printk: add new dev_err_probe() helpers

Browse Source 
[ Upstream commit dbbe7eaf0e ]

This is similar to dev_err_probe() but for cases where an ERR_PTR() or
ERR_CAST() is to be returned simplifying patterns like:

	dev_err_probe(dev, ret, ...);
	return ERR_PTR(ret)
or
	dev_err_probe(dev, PTR_ERR(ptr), ...);
	return ERR_CAST(ptr)
