Driver core: convert sound core to use struct device
Converts from using struct "class_device" to "struct device" making everything show up properly in /sys/devices/ with symlinks from the /sys/class directory. It also makes the struct sound_card to show up as a "real" device where all the different sound class devices are placed as childs and different card attribute files can hang off of. /sys/class/sound is still a flat directory, but the symlink targets of all devices belonging to the same card, point the the /sys/devices tree below the new card device object. Thanks to Kay for the updates to this patch. Signed-off-by: Kay Sievers <kay.sievers@novell.com> Acked-by: Jaroslav Kysela <perex@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
