[PATCH] ethernet: sun: Fix an error handling path in happy_meal_pci_probe()

[Christophe JAILLET]

A dma_free_coherent() call is missing in the error handling path of the
probe, as already done in the remove function.

dma_alloc_coherent() uses '&pdev->dev' and the remove function
'hp->dma_dev'.
This change is a copy&paste from the remove function, so I've left the
latter. It is not important because on line 3017 we have
"hp->dma_dev = &pdev->dev;" so both expression are the same.


I've not been able to find a Fixes tag because of the renaming of
function and files.
However, it looks old (before 2008)
