eeepc-laptop: enable camera by default
If we leave the camera disabled by default, userspace programs (e.g. Skype, Cheese) leave the user out in the cold saying that the machine "has no camera." Therefore, it's better to enable camera by default and let people who really don't want it just disable the thing. To reduce power usage you should enable USB autosuspend: echo -n auto > /sys/bus/usb/drivers/uvcvideo/*:*/../power/level Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Len Brown <len.brown@intel.com>
