pata_platform: Fix NULL pointer dereference
pata_platform: Fix NULL pointer dereference
pata_platform currently dereferences a NULL pointer in pata_platform_probe()
if pdev->dev.platform_data is set to NULL. This breakage was most likely
introduced by commit 5f45bc50976ee1f408f7171af155aec646655a37.
