Takashi Iwai c79442cc5a ALSA: ca0106: 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.

Fixes: 1656fa6ea2 ("ALSA: ca0106: Allocate resources with device-managed APIs")

* Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
* Version: 0.0.25
*
* FEATURES currently supported:
* Front, Rear and Center/LFE.
* Surround40 and Surround51.
* Capture from MIC an LINE IN input.
* SPDIF digital playback of PCM stereo and AC3/DTS works.
* (One can use a standard mono mini-jack to one RCA plugs cable.
* or one can use a standard stereo mini-jack to two RCA plugs cable.
* Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
* ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
* Notes on how to capture sound:
* The AC97 is used in the PLAYBACK direction.
* The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
* So, to record from the MIC, set the MIC Playback volume to max,
* unmute the MIC and turn up the MASTER Playback volume.
* So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
*
* The only playback controls that currently do anything are: -
* Analog Front
* Analog Rear
* Analog Center/LFE
* SPDIF Front
* SPDIF Rear
* SPDIF Center/LFE
*
* For capture from Mic in or Line in.
* Digital/Analog ( switch must be in Analog mode for CAPTURE. )
*
* CAPTURE feedback into PLAYBACK
*
* Changelog:
* Support interrupts per period.
* Removed noise from Center/LFE channel when in Analog mode.
* Rename and remove mixer controls.
* 0.0.6
* Use separate card based DMA buffer for periods table list.
* 0.0.7
* Change remove and rename ctrls into lists.
* 0.0.8
* Try to fix capture sources.
* 0.0.9
* Fix AC3 output.
* Enable S32_LE format support.
* 0.0.10
* Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
* 0.0.11
* Add Model name recognition.
* 0.0.12
* Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
* Remove redundent "voice" handling.
* 0.0.13
* Single trigger call for multi channels.
* 0.0.14
* Set limits based on what the sound card hardware can do.
* playback periods_min=2, periods_max=8
* capture hw constraints require period_size = n * 64 bytes.
* playback hw constraints require period_size = n * 64 bytes.
* 0.0.15
* Minor updates.
* 0.0.16
* Implement 192000 sample rate.
* 0.0.17
* Add support for SB0410 and SB0413.
* 0.0.18
* Modified Copyright message.
* 0.0.19
* Finally fix support for SB Live 24 bit. SB0410 and SB0413.
* The output codec needs resetting, otherwise all output is muted.
* 0.0.20
* Merge "pci_disable_device(pci);" fixes.
* 0.0.21
* Add 4 capture channels. (SPDIF only comes in on channel 0. )
* Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.)
* 0.0.22
* Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901
* 0.0.23
* Implement support for Line-in capture on SB Live 24bit.
* 0.0.24
* Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
* 0.0.25
* Powerdown SPI DAC channels when not in use
*
* BUGS:
* Some stability problems when unloading the snd-ca0106 kernel module.
