Would you mind trying the following fix:
diff --git a/drivers/mfd/lpc_ich.c b/drivers/mfd/lpc_ich.c
index 5c2ef41..fddc8e2 100644
--- a/drivers/mfd/lpc_ich.c
+++ b/drivers/mfd/lpc_ich.c
@@ -916,7 +916,7 @@ static int lpc_ich_probe(struct pci_dev *dev,
int ret;
bool cell_added = false;
- priv = kmalloc(GFP_KERNEL, sizeof(struct lpc_ich_priv));

if (!priv)
return -ENOMEM;
Cheers,
Samuel.
