2021-03-17ALSA: usb-audio: Fix "cannot get freq eq" errors on Dell AE515 sound barTakashi Iwai
commit fec60c3bc5d1713db2727cdffc638d48f9c07dc3 upstream. Dell AE515 sound bar (413c:a506) spews the error messages when the driver tries to read the current sample frequency, hence it needs to be on the list in snd_usb_get_sample_rate_quirk().

2021-03-17ALSA: hda: Avoid spurious unsol event handling during S3/S4Takashi Iwai
commit 5ff9dde42e8c72ed8102eb8cb62e03f9dc2103ab upstream. When HD-audio bus receives unsolicited events during its system suspend/resume (S3 and S4) phase, the controller driver may still try to process events although the codec chips are already (or yet) powered down. This might screw up the codec communication, resulting in CORB/RIRB errors. Such events should be rather skipped, as the codec chip status such as the jack status will be fully refreshed at the system resume time. Since we're tracking the system suspend/resume state in codec power.power_state field, let's add the check in the common unsol event handler entry point to filter out such events.

2021-03-17ALSA: hda/hdmi: Cancel pending works before suspendTakashi Iwai
commit eea46a0879bcca23e15071f9968c0f6e6596e470 upstream. The per_pin->work might be still floating at the suspend, and this may hit the access to the hardware at an unexpected timing. Cancel the work properly at the suspend callback for avoiding the buggy access. Note that the bug doesn't trigger easily in the recent kernels since the work is queued only when the repoll count is set, and usually it's only at the resume callback, but it's still possible to hit in theory.

2021-03-11ALSA: ctxfi: cthw20k2: fix mask on conf to allow 4 bitsColin Ian King
[ Upstream commit 26a9630c72ebac7c564db305a6aee54a8edde70e ] Currently the mask operation on variable conf is just 3 bits so the switch statement case value of 8 is unreachable dead code. The function daio_mgr_dao_init can be passed a 4 bit value, function dao_rsc_init calls it with conf set to: conf = (desc->msr & 0x7) | (desc->passthru << 3); so clearly when desc->passthru is set to 1 then conf can be at least 8. Fix this by changing the mask to 0xf.

2021-01-23ASoC: dapm: remove widget from dirty list on freeThomas Hebb
commit 5c6679b5cb120f07652418524ab186ac47680b49 upstream. A widget's "dirty" list_head, much like its "list" list_head, eventually chains back to a list_head on the snd_soc_card itself. This means that the list can stick around even after the widget (or all widgets) have been freed. Currently, however, widgets that are in the dirty list when freed remain there, corrupting the entire list and leading to memory errors and undefined behavior when the list is next accessed or modified. I encountered this issue when a component failed to probe relatively late in snd_soc_bind_card(), causing it to bail out and call soc_cleanup_card_resources(), which eventually called snd_soc_dapm_free() with widgets that were still dirty from when they'd been added.

commit 4ebd47037027c4beae99680bff3b20fdee5d7c1e upstream. The snd_seq_queue struct contains various flags in the bit fields. Those are categorized to two different use cases, both of which are protected by different spinlocks. That implies that there are still potential risks of the bad operations for bit fields by concurrent accesses.

2020-12-11ALSA: hda/generic: Add option to enforce preferred_dacs pairsTakashi Iwai
commit 242d990c158d5b1dabd166516e21992baef5f26a upstream. The generic parser accepts the preferred_dacs[] pairs as a hint for assigning a DAC to each pin, but this hint doesn't work always effectively. Currently it's merely a secondary choice after the trial with the path index failed. This made sometimes it difficult to assign DACs without mimicking the connection list and/or the badness table. This patch adds a new flag, obey_preferred_dacs, that changes the behavior of the parser. As its name stands, the parser obeys the given preferred_dacs[] pairs by skipping the path index matching and giving a high penalty if no DAC is assigned by the pairs. This mode will help for assigning the fixed DACs forcibly from the codec driver.

2020-11-24ALSA: ctl: fix error path at adding user-defined element setTakashi Sakamoto
commit 95a793c3bc75cf888e0e641d656e7d080f487d8b upstream. When processing request to add/replace user-defined element set, check of given element identifier and decision of numeric identifier is done in "__snd_ctl_add_replace()" helper function. When the result of check is wrong, the helper function returns error code. The error code shall be returned to userspace application. Current implementation includes bug to return zero to userspace application regardless of the result. This commit fixes the bug.

2020-10-29ALSA: seq: oss: Avoid mutex lock for a long-time ioctlTakashi Iwai
[ Upstream commit 2759caad2600d503c3b0ed800e7e03d2cd7a4c05 ] Recently we applied a fix to cover the whole OSS sequencer ioctls with the mutex for dealing with the possible races. This works fine in general, but in theory, this may lead to unexpectedly long stall if an ioctl like SNDCTL_SEQ_SYNC is issued and an event with the far future timestamp was queued. For fixing such a potential stall, this patch changes the mutex lock applied conditionally excluding such an ioctl command. Also, change the mutex_lock() with the interruptible version for user to allow escaping from the big-hammer mutex.

[ Upstream commit c637fa151259c0f74665fde7cba5b7eac1417ae5 ] The unsol event handling code has a loop retrieving the read/write indices and the arrays without locking while the append to the array may happen concurrently. This may lead to some inconsistency. Although there hasn't been any proof of this bad results, it's still safer to protect the racy accesses. This patch adds the spinlock protection around the unsol handling loop for addressing it. Here we take bus->reg_lock as the writer side snd_hdac_bus_queue_event() is also protected by that lock.

[ Upstream commit 13774d81f38538c5fa2924bdcdfa509155480fa6 ] In snd_hdac_device_init pm_runtime_set_active is called to increase child_count in parent device. But when it is failed to build connection with GPU for one case that integrated graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be invoked to clean up a HD-audio extended codec base device. At this time the child_count of parent is not decreased, which makes parent device can't get suspended. This patch calls pm_runtime_set_suspended to decrease child_count in parent device in snd_hdac_device_exit to match with snd_hdac_device_init. pm_runtime_set_suspended can make sure that it will not decrease child_count if the device is already suspended.

commit 1b7ecc241a67ad6b584e071bd791a54e0cd5f097 upstream. Further investigation of the L-R swap problem on the MS2109 reveals that the problem isn't that the channels are swapped, but rather that they are swapped and also out of phase by one sample. In other words, the issue is actually that the very first frame that comes from the hardware is a half-frame containing only the right channel, and after that everything becomes offset. So introduce a new quirk field to drop the very first 2 bytes that come in after the format is configured and a capture stream starts. This puts the channels in phase and in the correct order.
