Message-ID: <20090724094115.GA18450@basil.fritz.box>
Date: Fri, 24 Jul 2009 11:41:15 +0200

Subject: [PATCH] Shut off pci_find_device warnings when the deprecated pci
functions are enabled.
Shut off pci_find_device warnings when the deprecated pci functions are enabled.
Shut off the long standing
linux/drivers/pci/search.c:144: warning: 'pci_find_device' is deprecated (declared at linux/drivers/pci/search.c:136)
linux/drivers/pci/search.c:144: warning: 'pci_find_device' is deprecated (declared at linux/drivers/pci/search.c:136)
warnings that appear on every build when CONFIG_PCI_LEGACY is enabled.
gcc warns for the use in EXPORT_SYMBOL
I moved these to a separate file and disabled the warning in the Makefile for that file.
