From 182ee45da083db4e3e621541ccf255bfa9652214 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Wed, 27 Oct 2021 16:59:00 -0700 Subject: Bluetooth: hci_sync: Rework hci_suspend_notifier This makes hci_suspend_notifier use the hci_*_sync which can be executed synchronously which is allowed in the suspend_notifier and simplifies a lot of the handling since the status of each command can be checked inline so no other work need to be scheduled thus can be performed without using of a state machine.
