pcmcia: i82092: fix i82092aa_pci_remove()
Smatch complains because the call to pci_set_drvdata(dev, &sockets[i].socket); is reading one step beyond the end of the sockets[] array. It will crash when we use it later. The only place which uses pci_get_drvdata() is i82092aa_pci_remove(). That function should loop through all the sockets and unregister them.
