When node is removed from IEEE 1394 bus, any transaction fails to the node. In the case, ALSA dice driver doesn't stop isochronous contexts even if they are running. As a result, null pointer dereference occurs in callback from the running context. This commit fixes the bug to release isochronous contexts always.

Recently we found the micmute led init state is not correct after freshly installing the ubuntu linux on a Lenovo AIO machine. The internal mic is not muted, but the micmute led is on and led mode is 'follow mute'. If we mute internal mic, the led is keeping on, then unmute the internal mic, the led is off. And from then on, the micmute led will work correctly. So the micmute led init state is not correct. The led is controlled by codec gpio (ALC233_FIXUP_LENOVO_LINE2_MIC_HOTKEY), in the patch_realtek, the gpio data is set to 0x4 initially and the led is on with this data. In the hda_generic, the led_value is set to 0 initially, suppose users set the 'capture switch' to on from user space and the micmute led should change to be off with this operation, but the check "if (val == spec->micmute_led.led_value)" in the call_micmute_led_update() will skip the led setting. To guarantee the led state will be set by the 1st time of changing "Capture Switch", set -1 to the init led_value. Cc: <stable@vger.kernel.org> Signed-off-by:

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.

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.

The HD-audio controller driver processes the unsolicited events via its work asynchronously, and this might be pending when the system goes to suspend. When a lengthy event handling like ELD byte reads is running, this might trigger unexpected accesses among suspend/resume procedure, typically seen with Nvidia driver that still requires the handling via unsolicited event verbs for ELD updates. This patch adds the flush of unsol_work to assure that pending events are processed before going into suspend. Buglink: https://bugzilla.suse.com/show_bug.cgi?id=1182377 Reported-and-tested-by:

The commit c02f77d3 ("ALSA: hda - Workaround for crackled sound on AMD controller (1022:1457)") introduced a few workarounds for the recent AMD HD-audio controller, and one of them is the forced BATCH PCM mode so that PulseAudio avoids the timer-based scheduling. This was thought to cover for some badly working applications, but this actually worsens for more others. In total, this wasn't a good idea to enforce it. This is a partial revert of the commit above for dropping the PCM BATCH enforcement part to recover from the regression again.

Move it into issue instead, and we can drop all of that code too. - Kill f_op->flush() usage. That was such a nasty hack that we had out of necessity, we no longer need it. - Following from ->flush() removal, we can also drop various bits of ctx state related to SQPOLL and cancelations. - Fix an issue with IOPOLL retry, which originally was fallout from a filemap change (removing iov_iter_revert()), but uncovered an issue with iovec re-import too late. - Fix an issue with system suspend. - Use xchg() for fallback work, instead of cmpxchg(). - Properly destroy io-wq on exec. - Add create_io_thread() core helper, and use that in io-wq and io_uring. This allows us to remove various silly completion events related to thread setup. - A few error handling fixes.

We have this weird true/false return from parking, and then some of the callers decide to look at that. It can lead to unbalanced parks and sqd locking. Have the callers check the thread status once it's parked. We know we have the lock at that point, so it's either valid or it's NULL. Fix race with parking on thread exit. We need to be careful here with ordering of the sdq->lock and the IO_SQ_THREAD_SHOULD_PARK bit. Rename sqd->completion to sqd->parked to reflect that this is the only thing this completion event doesn. Signed-off-by:

It doesn't make sense to wait for more events to come in, if we can't even flush the overflow we already have to the ring. Return -EBUSY for that condition, just like we do for attempts to submit with overflow pending. Cc: stable@vger.kernel.org # 5.11 Signed-off-by:

This allows us to do task creation and setup without needing to use completions to try and synchronize with the starting thread. Get rid of the old io_wq_fork_thread() wrapper, and the 'wq' and 'worker' startup completion events - we can now do setup before the task is running. Signed-off-by:

In case we have already established connection to nvmf target, it shouldn't be allowed to change the model_number. E.g. if someone will identify ctrl and get model_number of "my_model" later on will change the model_numbel via configfs to "my_new_model" this will break the NVMe specification for "Get Log Page – Persistent Event Log" that refers to Model Number as: "This field contains the same value as reported in the Model Number field of the Identify Controller data structure, bytes 63:24." Although it doesn't mentioned explicitly that this field can't be changed, we can assume it. So allow setting this field only once: using configfs or in the first identify ctrl operation.

Currently kato is initialized to NVME_DEFAULT_KATO for both discovery & i/o controllers. This is a problem specifically for non-persistent discovery controllers since it always ends up with a non-zero kato value. Fix this by initializing kato to zero instead, and ensuring various controllers are assigned appropriate kato values as follows: non-persistent controllers - kato set to zero persistent controllers - kato set to NVMF_DEV_DISC_TMO (or any positive int via nvme-cli) i/o controllers - kato set to NVME_DEFAULT_KATO (or any positive int via nvme-cli) Signed-off-by:

The hwmon pointer wont be NULL if the registration fails. Though the exit code path will assign it to ctrl->hwmon_device. Later nvme_hwmon_exit() will try to free the invalid pointer. Avoid this by returning the error code from hwmon_device_register_with_info(). Fixes: ed7770f6 ("nvme/hwmon: rework to avoid devm allocation") Signed-off-by:
