ALSA: use card device as parent for jack input-devices
This moves the jack devices from the PCI device into the ALSA card device, which makes it easier for userspace to find all devices belonging to a specific card while granting access to logged-in users. Jack input devices from sound cards can now simply be matched with udev by doing: SUBSYSTEM="input", SUBSYSTEMS="sound", ... ls -l /sys/devices/pci0000:00/0000:00:1b.0/sound/card0 controlC0 device -> ../../../0000:00:1b.0 id input10 input11 input8 input9 number pcmC0D0c pcmC0D0p pcmC0D1p power subsystem -> ../../../../../class/sound uevent Cc: Lennart Poettering <lennart@0pointer.de> Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
