Subject: [027/107] drm: populate irq_by_busid-member for pci

2.6.39-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Wolfram Sang <w.sang@...gutronix.de>

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.

[airlied: made function static also]
