Again no functional changes, but only code clean up. Use a standard macro for initializing the procfs entries, also drop the info entries stored in dsp_spos_instance, as they are removed recursively by a single snd_info_free_entry() calls. Reviewed-by:

The creation of card's id proc file can be moved gracefully into info.c. Also, the assignment of card->proc_id is superfluous and can be dropped. So let's do it. Basically this is no functional change but code refactoring, but one potential behavior change is that now it returns properly the error code from snd_info_card_register(), which is a good thing (tm).

The calls of snd_info_register() are superfluous and should be avoided at the procfs creation time. They are called at the end of the whole initialization via snd_card_register(). This patch drops such superfluous calls, as well as dropping the superfluous setup of SNDRV_INFO_CONTENT_TEXT. Reviewed-by:

Make sure that all children entries are registered by a single call of snd_info_register(). OTOH, don't register if a parent isn't registered yet. This allows us to create the whole procfs tree in a shot at the last stage of card registration phase in a later patch. Signed-off-by: -

We used to pass NULL to memory allocators for ISA devices due to historical reasons. But we prefer rather a proper device object to be assigned, so let's fix it by replacing snd_dma_isa_data() call with card->dev reference, and kill snd_dma_isa_data() definition. Reviewed-by:

The DMA API generally relies on a struct device to work properly, and only barely works without one for legacy reasons. Pass the easily available struct device from the platform_device to remedy this. Also use GFP_KERNEL instead of GFP_USER as the gfp_t for the memory allocation, as we should treat this allocation as a normal kernel one. Signed-off-by:

Currently the registration and free of beep input device was done manually from the register and the disconnect callbacks of the assigned codec object. This seems working in most cases, but this may be a cause of some races at probe. Moreover, due to these manual calls, the total code became unnecessarily lengthy. This patch rewrites the beep registration code to follow the standard sound device object style. This allows us reducing the code, in addition to avoiding the nested device registration calls.

The init sequence for ALC294 headphone stuff is needed not only for the boot up time but also for the resume from hibernation, where the device is switched from the boot kernel without sound driver to the suspended image. Since we record the PM event in the device power_state field, we can now recognize the call pattern and apply the sequence conditionally. Signed-off-by: -

Currently we deal with single codec and suspend codec callbacks for all S3, S4 and runtime PM handling. But it turned out that we want distinguish the call patterns sometimes, e.g. for applying some init sequence only at probing and restoring from hibernate. This patch slightly modifies the common PM callbacks for HD-audio codec and stores the currently processed PM event in power_state of the codec's device.power field, which is currently unused. The codec callback can take a look at this event value and judges which purpose it's being called. Signed-off-by: -

Fix hp_pin always no value. [More notes on the changes: The hp_pin value that is referred in alc294_hp_init() is always zero at the moment the function gets called, hence this is actually useless as in the current code. And, this kind of init sequence should be called from the codec init callback, instead of the parser function. So, the first fix in this patch to move the call call into its own init_hook. OTOH, this function is needed to be called only once after the boot, and it'd take too long for invoking at each resume (where the init callback gets called). So we add a new flag and invoke this only once as an additional fix. The one case is still not covered, though: S4 resume. But this change itself won't lead to any regression in that regard, so we leave S4 issue as is for now and fix it later. -- tiwai ] Fixes: bde1a745 ("ALSA: hda/realtek - Fixed headphone issue for ALC700") Signed-off-by:

XMOS/Thesycon family of USB Audio Class firmware flags DSD altsetting separate from the PCM ones. Thus the DSD altsetting can be auto-detected based on the flag and doesn't need maintaining specific altsetting whitelist. In addition, static VID:PID-to-altsetting whitelisting causes problems when firmware update changes the altsetting, or same VID:PID is reused for another device that has different kind of firmware. This patch removes existing explicit whitelist mappings for XMOS VID (0x20b1) and Thesycon VID (0x152a). Also corrects placement of Hegel HD12 and NuPrime DAC-10 to keep list sorted based on VID.

Duende Classic was produced by Solid State Logic in 2006, as a first model of Duende DSP series. The following model, Duende Mini was produced in 2008. They are designed to receive isochronous packets for PCM frames via IEEE 1394 bus, perform signal processing by downloaded program, then transfer isochronous packets for converted PCM frames. These two models includes the same embedded board, consists of several ICs below: - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer - Altera MAX 3000A CPLD for programs - Analog devices, SHARC ADSP-21363 for signal processing (4 chips) This commit adds support for the two models to ALSA dice driver. Like support for the other devices, packet streaming is just available. Userspace applications should be developed if full features became available; e.g. program uploader and parameter controller. $ ./hinawa-config-rom-printer /dev/fw1 { 'bus-info': { 'adj': False, 'bmc': False, 'chip_ID': 349771402425, 'cmc': True, 'cyc_clk_acc': 255, 'generation': 1, 'imc': True, 'isc': True, 'link_spd': 2, 'max_ROM': 1, 'max_rec': 512, 'name': '1394', 'node_vendor_ID': 20674, 'pmc': False}, 'root-directory': [ ['VENDOR', 20674], ['DESCRIPTOR', 'Solid State Logic'], ['MODEL', 112], ['DESCRIPTOR', 'Duende board'], [ 'NODE_CAPABILITIES', { 'addressing': {'64': True, 'fix': True, 'prv': True}, 'misc': {'int': False, 'ms': False, 'spt': True}, 'state': { 'atn': False, 'ded': False, 'drq': True, 'elo': False, 'init': False, 'lst': True, 'off': False}, 'testing': {'bas': False, 'ext': False}}], [ 'UNIT', [ ['SPECIFIER_ID', 20674], ['VERSION', 1], ['MODEL', 112], ['DESCRIPTOR', 'Duende board']]]]} Signed-off-by:

When the trigger=off is passed for a PCM OSS stream, it sets the start_threshold of the given substream to the boundary size, so that it won't be automatically started. This can be problematic for a capture stream, unfortunately, as detected by syzkaller. The scenario is like the following: - In __snd_pcm_lib_xfer() that is invoked from snd_pcm_oss_read() loop, we have a check whether the stream was already started or the stream can be auto-started. - The function at this check returns 0 with trigger=off since we explicitly disable the auto-start. - The loop continues and repeats calling __snd_pcm_lib_xfer() tightly, which may lead to an RCU stall. This patch fixes the bug by simply allowing the wait for non-started stream in the case of OSS capture. For native usages, it's supposed to be done by the caller side (which is user-space), hence it returns zero like before. (In theory, __snd_pcm_lib_xfer() could wait even for the native API usage cases, too; but I'd like to stay in a safer side for not breaking the existing stuff for now.)

This patch adds quirk VID/PID IDs for the Opus #3 DAP (made by 'The Bit') in order to enable Native DSD support. [ NOTE: this could be handled in the generic way with fp->dvd_raw if we add 0x10cb to the vendor whitelist, but since 0x10cb shows a different vendor name (Erantech), put to the individual entry at this time -- tiwai ] Signed-off-by:

An open-coded error path in __snd_pcm_lib_xfer() can be replaced with the simple goto to the common error path. This also makes the error handling more consistent, i.e. when some samples have been already processed, return that size instead of the error code. Signed-off-by: -
