I just realised that we cannot merge this series (the second acpi patch) until the hci_intel driver gains serdev support or otherwise PM will break for those devices. Specifically, the hci_intel driver uses similar hacks as the hci_bcm driver does for PM, so we need something like Hans's hci_bcm series also for hci_intel before we can do the switch. Hopefully there are no more of these...
