Subject: [patch] pcmcia: i82092: fix i82092aa_pci_remove()
Date: Fri, 14 Dec 2012 15:01:08 +0000 [thread overview]
Message-ID: <20121214150107.GA15839@elgon.mountain> (raw)
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.
