Since we covered all callers with NULL device pointer, let's catch the remaining calls with NULL and warn explicitly. Acked-by:

We should pass a proper non-NULL device object to memory allocators although it was accepted in the past. The card->dev points to the most appropriate device object in such a case, so let's put it. Acked-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:Takashi Sakamoto <o-takashi@sakamocchi.jp> 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: -

This patch changes the parent pointer assignment of snd_info_entry object to be always non-NULL. More specifically,check the parent argument in snd_info_create_module_entry() & co, and assign snd_proc_root if NULL is passed there. This assures that the proc object is always freed when the root is freed, so avoid possible memory leaks. For example, some error paths (e.g. snd_info_register() error at snd_minor_info_init()) may leave snd_info_entry object although the proc file itself is freed. Signed-off-by:
