Takashi Iwai 27a0963f9c ALSA: via82xx: Fix the missing snd_card_free() call at probe error 
The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature.  Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.

/*
* Changes:
*
* Dec. 19, 2002 Takashi Iwai <tiwai@suse.de>
* - use the DSX channels for the first pcm playback.
* (on VIA8233, 8233C and 8235 only)
* this will allow you play simultaneously up to 4 streams.
* multi-channel playback is assigned to the second device
* on these chips.
* - support the secondary capture (on VIA8233/C,8235)
* - SPDIF support
* the DSX3 channel can be used for SPDIF output.
* on VIA8233A, this channel is assigned to the second pcm
* playback.
* the card config of alsa-lib will assign the correct
* device for applications.
* - clean up the code, separate low-level initialization
* routines for each chipset.
*
* Sep. 26, 2005 Karsten Wiese <annabellesgarden@yahoo.de>
* - Optimize position calculation for the 823x chips.
