[MTD] [NAND] drivers/mtd/nand/pasemi_nand.c: Add missing pci_dev_put
pci_get_device increments a reference count that should be decremented using pci_dev_put. The semantic patch that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S,S1; position p1,p2,p3; expression E,E1; type T,T1; expression *ptr != NULL; @@ ( if ((x@p1 = pci_get_device(...)) == NULL) S | x@p1 = pci_get_device(...); ) ... when != pci_dev_put(...,(T)x,...) when != if (...) { <+... pci_dev_put(...,(T)x,...) ...+> } when != true x == NULL || ... when != x = E when != E = (T)x when any ( if (x == NULL || ...)
