From d37363409bacd1142c6e49edfb3e1f8b153d47dc Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 8 May 2007 00:39:28 -0700 Subject: [PATCH] nvidiafb/rivafb: switch to pci_get refcounting Switch to pci_get refcounting APIs [adaplas] Fix a long-standing bug where the return value of pci_find_slot()/pci_get_bus_and_slot() is ignored.
