2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------ From: Wolfram Sang <[email protected]> commit 45e97ab65026a3391cb2c938f834ca5db4d2e5b3 upstream. Commit 8410ea (drm: rework PCI/platform driver interface) implemented drm_pci_irq_by_busid() but forgot to make it available in the drm_pci_bus-struct. This caused a freeze on my Radeon9600-equipped laptop when executing glxgears. Thanks to Michel for noticing the flaw.
