Subject: [PATCH 0/2] Bluetooth: Suspend related bugfixes


Hi Marcel,

After further automated testing of the upstreamed suspend patches,
I found two issues:
- A failure in PM_SUSPEND_PREPARE wasn't calling PM_POST_SUSPEND.
  I misread the docs and thought it would call it for all notifiers
  already run but it only does so for the ones that returned
  successfully from PM_SUSPEND_PREPARE.
- hci_conn_complete_evt wasn't completing on auto-connects (an else
  block was removed during a refactor incorrectly)

With the following patches, I've run a suspend stress test on a couple
of Chromebooks for several dozen iterations (each) successfully.

Thanks
Abhishek
