drivers/pcmcia: add missing pci_dev_get
pci_get_slot does a pci_dev_get, so pci_dev_put needs to be called in an error case. An extract of the semantic match used to find the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type find1.T,T1,T2; identifier find1.E; statement find1.S; expression x1,x2,x3; expression find1.test; int ret != 0; @@ T E; ...
