From c5522d02fe23ef2420a6519bf9e8599565082f2f Mon Sep 17 00:00:00 2001 From: Abhishek Pandit-Subedi Date: Wed, 29 Jul 2020 16:17:43 -0700 Subject: [PATCH] Revert "Bluetooth: btusb: Disable runtime suspend on Realtek devices" This reverts commit 4b45578973904f5aad4373bd24ffefbdfe553e71. Testing this change on a board with RTL8822CE, I found that enabling autosuspend has no effect on the stability of the system. The board continued working after autosuspend, suspend and reboot. The original commit makes it impossible to enable autosuspend on working systems so it should be reverted. Disabling autosuspend should be done via module param or udev in userspace instead.
