[ALSA] sound/core/memalloc.c: Add missing pci_dev_put
There should be a pci_dev_put when breaking out of a loop that iterates
over calls to pci_get_device and similar functions.
In this case, the return under the initial if needs a pci_dev_put in the
same way that the return under the subsequent for loop has a pci_dev_put.
This was fixed using the following semantic patch.
// <smpl>
@@
type T;
identifier d;
expression e;
@@
T *d;
...
while ((d = \(pci_get_device\|pci_get_device_reverse\|pci_get_subsys\|pci_get_class\)(..., d)) != NULL)
{... when != pci_dev_put(d)
when != e = d
(
return d;
|
+ pci_dev_put(d);
? return ...;
)
...}
// </smpl>
