-Subject: [PATCH] sound/usb: call usb_autopm_get_interface() for
- devices that should not be suspended
-
-Webcams with microphones are composite devices, and autosuspend is set
-at the device level. If uvcvideo is probed after snd-usb-audio, the effect
-of the quirk applied by snd-usb-audio is undone by uvcvideo's global
-application of autosuspend.
-
-Incrementing the interface's PM refcount in such cases prevents runtime PM
-from happening, thus the device is left active.
