6.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx> [ Upstream commit cffa8e83df9fe525afad1e1099097413f9174f57 ] The pci state was saved, but not restored. Restore right after the power state transition request like every other driver. v2: Use right fixes tag, since this was there initialy, but accidentally removed.
