There should be a pci_dev_put when breaking out of a loop that iterates
over calls to pci_get_device and similar functions.
This was fixed using the following semantic patch.
// <smpl>
@@
identifier d;
type T;
expression e;
iterator for_each_pci_dev;
@@
T *d;
...
for_each_pci_dev(d)
{... when != pci_dev_put(d)
when != e = d
(
return d;
|
+ pci_dev_put(d);
? return ...;
)
...}
// </smpl>
