[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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
