Rene Herman dcccdd938e [ALSA] unregister platform device again if probe was unsuccessful 
Unregister the platform device again if the probe was unsuccessful.

This restores the behaviour of not loading the driver on probe() failure.

/*
* NOTES
*
* The extended registers contain mixer settings which are largely
* untapped for the time being.
*
* MPU401 and SPDIF are not supported yet. I don't have the hardware
* to aid in coding and testing, so I won't bother.
*
* To quickly load the module,
*
* modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
* sbdma16=5 wssport=0x530 wssirq=11 wssdma=0
*
* This card has two mixers and two PCM devices. I've cheesed it such
* that recording and playback can be done through the same device.
* The driver "magically" routes the capturing to the AD1848 codec,
* and playback to the SB16 codec. This allows for full-duplex mode
* to some extent.
* The utilities in alsa-utils are aware of both devices, so passing
* the appropriate parameters to amixer and alsactl will give you
* full control over both mixers.
