Hans de Goede 05a524b97d Bluetooth: Add new HCI_QUIRK_NO_SUSPEND_NOTIFIER quirk ... [ Upstream commit 219991e6be ] Some devices, e.g. the RTL8723BS bluetooth part, some USB attached devices, completely drop from the bus on a system-suspend. These devices will have their driver unbound and rebound on resume (when the dropping of the bus gets detected) and will show up as a new HCI after resume. These devices do not benefit from the suspend / resume handling work done by the hci_suspend_notifier. At best this unnecessarily adds some time to the suspend/resume time. But this may also actually cause problems, if the code doing the driver unbinding runs after the pm-notifier then the hci_suspend_notifier code will try to talk to a device which is now in an uninitialized state. This commit adds a new HCI_QUIRK_NO_SUSPEND_NOTIFIER quirk which allows drivers to opt-out of the hci_suspend_notifier when they know beforehand that their device will be fully re-initialized / reprobed on resume.
