em28xx: register device to soundcard for sysfs
From: Nicola Soranzo <nsoranzo@tiscali.it>
As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should
set the struct device for the card before registering the card instance.
This will add the correct /sys/class/sound/cardN/device symlink, so HAL
can see the device and ConsoleKit sets its ACL permissions for the
logged-in user.
For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2),
this patch fixes errors like:
ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card
Error opening audio: Permission denied
when running mplayer as a normal user.
Priority: normal
