Subject: [PATCH 5.18 01/88] Bluetooth: Always set event mask on suspend

From: Abhishek Pandit-Subedi <abhishekpandit@...omium.org>

commit ef61b6ea154464fefd8a6712d7a3b43b445c3d4a upstream.

When suspending, always set the event mask once disconnects are
successful. Otherwise, if wakeup is disallowed, the event mask is not
set before suspend continues and can result in an early wakeup.
