From 4e0a1d8b06751d9ea8357e1f29f6b31465856665 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Tue, 2 May 2023 15:11:59 -0700 Subject: [PATCH] Bluetooth: btusb: Don't suspend when there are connections This checks if there are connections before suspending since that may disrupt the connections making it stop receiving any data if remote wakeup is not enabled.
