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.
