drivers/ide/cy82c693.c: Add missing pci_dev_put
Pci_get_slot calls pci_dev_get, so pci_dev_put is needed before leaving the
function in the case where pci_get_slot is locally used.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
local idexpression x;
expression e;
@@
*x = pci_get_slot(...)
... when != true x == NULL
when != pci_dev_put(x)
when != e = x
when != if (x != NULL) {<+... pci_dev_put(x); ...+>}
*return ...;
// </smpl>
