Fixed that in my tree already. But I now have six err=-ENOMEM peppered
all over the probe code. Still, if it makes it more readable ...

Yes, I've belatedly realized that now.
The major obstacle now seems to be dynamic allocation of the driver
private data and storing a pointer to that in a way that it can be
retrieved using just the esp pointer. dev_set_drvdata(esp->dev, zep)
causes the module load to crash ...
