2021-03-25dt-bindings: phy: mediatek: hdmi-phy: modify compatible itemsChunfeng Yun
mt7623-hdmi-tx is compatible to mt2701-hdmi-tx, and the compatible "mediatek,mt7623-hdmi-tx" is not supported in driver, in fact uses "mediatek,mt2701-hdmi-tx" instead on MT7623, so changes the compatible items to make dependence clear.

Pull io_uring fixes from Jens Axboe: "A bit of a mix between fallout from the worker change, cleanups and reductions now possible from that change, and fixes in general. In detail: - Fully serialize manager and worker creation, fixing races due to that. - Clean up some naming that had gone stale. - SQPOLL fixes. - Fix race condition around task_work rework that went into this merge window. - Implement unshare. Used for when the original task does unshare(2) or setuid/seteuid and friends, drops the original workers and forks new ones. - Drop the only remaining piece of state shuffling we had left, which was cred. 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. This should be the grunt of fixes necessary for the new workers, next week should be quieter. We've got a pending series from Pavel on cancelations, and how tasks and rings are indexed. Outside of that, should just be minor fixes.

2021-03-05io_uring: make SQPOLL thread parking sanerJens Axboe
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: Jens Axboe <axboe@kernel.dk>
2021-03-05io-wq: kill hashed waitqueue before manager exitsJens Axboe
If we race with shutting down the io-wq context and someone queueing a hashed entry, then we can exit the manager with it armed. If it then triggers after the manager has exited, we can have a use-after-free where io_wqe_hash_wake() attempts to wake a now gone manager process. Move the killing of the hashed write queue into the manager itself, so that we know we've killed it before the task exits.

2021-03-05io_uring: clear IOCB_WAITQ for non -EIOCBQUEUED returnJens Axboe
The callback can only be armed, if we get -EIOCBQUEUED returned. It's important that we clear the WAITQ bit for other cases, otherwise we can queue for async retry and filemap will assume that we're armed and return -EAGAIN instead of just blocking for the IO.

2021-03-05io_uring: don't keep looping for more events if we can't flush overflowJens Axboe
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: Jens Axboe <axboe@kernel.dk>
2021-03-05io_uring: move to using create_io_thread()Jens Axboe
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: Jens Axboe <axboe@kernel.dk>

2021-03-05nvmet: model_number must be immutable once setMax Gurtovoy
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.

2021-03-05nvme-fabrics: fix kato initializationMartin George
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: Martin George <marting@netapp.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2021-03-05nvme-hwmon: Return error code when registration failsDaniel Wagner
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().

2021-03-05nvme-pci: mark Kingston SKC2000 as not supporting the deepest power stateZoltán Böszörményi
My 2TB SKC2000 showed the exact same symptoms that were provided in 538e4a8c57 ("nvme-pci: avoid the deepest sleep state on Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed cold boot to get it back. According to some sources, the A2000 is simply a rebadged SKC2000 with a slightly optimized firmware. Adding the SKC2000 PCI ID to the quirk list with the same workaround as the A2000 made my laptop survive a 5 hours long Yocto bootstrap buildfest which reliably triggered the SSD lockup previously.
