+From 20eeb02a0a489e35de0830b2d61f09d43763c982 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Bluetooth: btusb: Add a Kconfig option to enable USB
+ autosuspend by default
+
+On many laptops the btusb device is the only USB device not having USB
+autosuspend enabled, this causes not only the HCI but also the USB
+controller to stay awake, together using aprox. 0.4W of power.
+
+Modern ultrabooks idle around 6W (at 50% screen brightness), 3.5W for
+Apollo Lake devices. 0.4W is a significant chunk of this (7 / 11%).
+
+The btusb driver already contains code to allow enabling USB autosuspend,
+but currently leaves it up to the user / userspace to enable it. This
+means that for most people it will not be enabled, leading to an
+unnecessarily high power consumption.
+
+Since enabling it is not entirely without risk of regressions, this
+commit adds a Kconfig option so that Linux distributions can choose to
+enable it by default. This commit also adds a module option so that when
+distros receive bugs they can easily ask the user to disable it again
+for easy debugging.
