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. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Jeff Garzik <jeff@garzik.org>
