[ Upstream commit bae3ce4942980d5f7b2b9855f4a2db0c00f9dfbd ] For improving readability, convert camelCase fields, variables and functions to the plain names with underscore. Also align the macros to be capital letters. All done via sed, no functional changes. Note that you'll still see many coding style issues even after this patch; the fixes will follow.

2021-07-14ALSA: usb-audio: scarlett2: Fix wrong resume callTakashi Iwai3-1/+10
commit 785b6f29a795f109685f286b91e0250c206fbffb upstream. The current way of the scarlett2 mixer code managing the usb_mixer_elem_info object is wrong in two ways: it passes its internal index to the head.id field, and the val_type field is uninitialized. This ended up with the wrong execution at the resume because a bogus unit id is passed wrongly. Also, in the later code extensions, we'll have more mixer elements, and passing the index will overflow the unit id size (of 256). This patch corrects those issues. It introduces a new value type, USB_MIXER_BESPOKEN, which indicates a non-standard mixer element, and use this type for all scarlett2 mixer elements, as well as initializing the fixed unit id 0 for avoiding the overflow.

Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change.

2021-05-26ALSA: line6: Fix racy initialization of LINE6 MIDITakashi Iwai3-11/+4
commit 05ca447630334c323c9e2b788b61133ab75d60d3 upstream. The initialization of MIDI devices that are found on some LINE6 drivers are currently done in a racy way; namely, the MIDI buffer instance is allocated and initialized in each private_init callback while the communication with the interface is already started via line6_init_cap_control() call before that point. This may lead to Oops in line6_data_received() when a spurious event is received, as reported by syzkaller. This patch moves the MIDI initialization to line6_init_cap_control() as well instead of the too-lately-called private_init for avoiding the race. Also this reduces slightly more lines, so it's a win-win change.

[ Upstream commit cfd577acb769301b19c31361d45ae1f145318b7a ] Currently when the call to usb_urb_ep_type_check fails (returning -EINVAL) the error return path returns -ENOMEM via the exit label "error". Other uses of the same error exit label set the err variable to -ENOMEM but this is not being used. I believe the original intent was for the error exit path to return the value in err rather than the hard coded -ENOMEM, so return this rather than the hard coded -ENOMEM.

2021-05-11ALSA: usb-audio: Explicitly set up the clock selectorTakashi Iwai1-4/+14
commit d2e8f641257d0d3af6e45d6ac2d6f9d56b8ea964 upstream. In the current code, we have some assumption that the audio clock selector has been set up implicitly and don't want to touch it unless it's really needed for the fallback autoclock setup. This works for most devices but some seem having a problem. Partially this was covered for the devices with a single connector at the initialization phase (commit 086b957cc17f "ALSA: usb-audio: Skip the clock selector inquiry for single connections"), but also there are cases where the wrong clock set up is kept silently. The latter seems to be the cause of the noises on Behringer devices. In this patch, we explicitly set up the audio clock selector whenever the appropriate node is found.

Apology for that. Changing supports_autosuspend in driver is too late for disabling autosuspend, because it was already used by USB probe routine, so it can break the balance on the following code that depends on supports_autosuspend. Fix it by using usb_disable_autosuspend() helper, and balance the suspend count in disconnect callback.

2021-03-17ALSA: usb-audio: Apply the control quirk to Plantronics headsetsTakashi Iwai1-3/+3
commit 06abcb18b3a021ba1a3f2020cbefb3ed04e59e72 upstream. Other Plantronics headset models seem requiring the same workaround as C320-M to add the 20ms delay for the control messages, too. Apply the workaround generically for devices with the vendor ID 0x047f. Note that the problem didn't surface before 5.11 just with luck. Since 5.11 got a big code rewrite about the stream handling, the parameter setup procedure has changed, and this seemed triggering the problem more often.

[ Upstream commit fee03efc69345344c8851596d74d93199b175bfe ] This commit adds mixer quirks for the Pioneer DJM-900NXS2 mixer. This device has 6 capture channels, 5 of them allow setting the signal source. This adds controls for these, similar to the DJM-250Mk2. However, playpack channels are not controllable via software like on the 250Mk2, as they can only be set manually on the mixing console. Read-only controls showing the currently selected playback channels are omitted.

[ Upstream commit a07df82c799013236aa90a140785775eda9f9523 ] This allows for N different devices to use the pioneer mixer quirk for setting capture/record type and recording level. The impementation has not changed much with the exception of an additional mask on private_value to allow storing of a device index: DEVICE MASK 0xff000000 GROUP_MASK 0x00ff0000 VALUE_MASK 0x0000ffff This could be improved by changing the arrays of wValues for each channel to contain named definitions (e.g. SND_DJM_CAP_LINE). It would improve readability and perhaps would allow using the same array for multiple channels. The channel number can be specified on the control next to the wIndex. Feedback is very much appreciated as I'm not the most proficient C programmer but am learning as I go.

2021-03-09ALSA: usb-audio: Drop bogus dB range in too low levelTakashi Iwai1-0/+11
commit 21cba9c5359dd9d1bffe355336cfec0b66d1ee52 upstream. Some USB audio firmware seem to report broken dB values for the volume controls, and this screws up applications like PulseAudio who blindly trusts the given data. For example, Edifier G2000 reports a PCM volume from -128dB to -127dB, and this results in barely inaudible sound. This patch adds a sort of sanity check at parsing the dB values in USB-audio driver and disables the dB reporting if the range looks bogus. Here, we assume -96dB as the bottom line of the max dB. Note that, if one can figure out that proper dB range later, it can be patched in the mixer maps.

commit fb3c293b82c31a9a68fbcf4e7a45fadd8a47ea2b upstream. The commit f274baa49be6 ("ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffers") introduced the mode to allocate coherent pages for PCM buffers, and it used bus->controller device as its DMA device. It turned out, however, that bus->sysdev is a more appropriate device to be used for DMA mapping in HCD code. This patch corrects the device reference accordingly. Note that, on most platforms, both point to the very same device, hence this patch doesn't change anything practically. But on platforms like xhcd-plat hcd, the change becomes effective.

commit c06ccf3ebb7503706ea49fd248e709287ef385a3 upstream. The calculation of in_cables and out_cables bitmaps are done with the bit shift by the value from the descriptor, which is an arbitrary value, and can lead to UBSAN shift-out-of-bounds warnings. Fix it by filtering the bad descriptor values with the check of the upper bound 0x10 (the cable bitmaps are 16 bits).

commit c6dde8ffd071aea9d1ce64279178e470977b235c upstream. The current channel-map control implementation in USB-audio driver may lead to an error message like "control 3:0:0:Playback Channel Map:0: access overflow" when CONFIG_SND_CTL_VALIDATION is set. It's because the chmap get callback clears the whole array no matter which count is set, and rather the false-positive detection.

2020-10-27ALSA: usb-audio: Add implicit feedback quirk for Zoom UAC-2Keith Winstein1-0/+4
The Zoom UAC-2 USB audio interface provides an async playback endpoint ("1 OUT (ASYNC)") and capture endpoint ("2 IN (ASYNC)"), both with 2-channel S32_LE in 44.1, 48, 88.2, 96, 176.4, or 192 kilosamples/s. The device provides explicit feedback to adjust the host's playback rate, but the feedback appears unstable and biased relative to the device's capture rate. "alsaloop -t 1000" experiences playback underruns and tries to resample the captured audio to match the varying playback rate. Forcing the kernel to use implicit feedback appears to produce more stable results. This causes the host to transmit one playback sample for each capture sample received. (Zoom North America has been notified of this change.)
