From 36c286d5a45731d957d02c317ee2ce775e856765 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 14 Dec 2012 18:01:08 +0300 Subject: [PATCH] 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.
