2021-10-20spi: altera: Change to dynamic allocation of spi idRuss Weight
The spi-altera driver has two flavors: platform and dfl. I'm seeing a case where I have both device types in the same machine, and they are conflicting on the SPI ID: ... kernel: couldn't get idr ... kernel: WARNING: CPU: 28 PID: 912 at drivers/spi/spi.c:2920 spi_register_controller.cold+0x84/0xc0a Both the platform and dfl drivers use the parent's driver ID as the SPI ID. In the error case, the parent devices are dfl_dev.4 and subdev_spi_altera.4.auto. When the second spi-master is created, the failure occurs because the SPI ID of 4 has already been allocated. Change the ID allocation to dynamic (by initializing bus_num to -1) to avoid duplicate SPI IDs.

2021-10-19nvme: loop: clear NVME_CTRL_ADMIN_Q_STOPPED after admin queue is reallocatedMing Lei
The nvme-loop's admin queue may be freed and reallocated, and we have to reset the flag of NVME_CTRL_ADMIN_Q_STOPPED so that the flag can match with the quiesce state of the admin queue. nvme-loop is the only driver to reallocate request queue, and not see such usage in other nvme drivers.

2021-10-19nvme: paring quiesce/unquiesceMing Lei
The current blk_mq_quiesce_queue() and blk_mq_unquiesce_queue() always stops and starts the queue unconditionally. And there can be concurrent quiesce/unquiesce coming from different unrelated code paths, so unquiesce may come unexpectedly and start queue too early. Prepare for supporting concurrent quiesce/unquiesce from multiple contexts, so that we can address the above issue. NVMe has very complicated quiesce/unquiesce use pattern, add one atomic bit for makeiing sure that blk-mq quiece/unquiesce is always called in pair.

2021-10-19RDMA/irdma: Do not hold qos mutex twice on QP resumeMustafa Ismail
When irdma_ws_add fails, irdma_ws_remove is used to cleanup the leaf node. This lead to holding the qos mutex twice in the QP resume path. Fix this by avoiding the call to irdma_ws_remove and unwinding the error in irdma_ws_add. This skips the call to irdma_tc_in_use function which is not needed in the error unwind cases.

2021-10-19drm/amd/display: correct apg audio channel enable golden valueWenjing Liu
Hardware team has recommended to generically hard code this register to 0xFF as part of the effort to eventually remove this control. However we set it to 0xF instead. This causes 4 of audio 8ch to be muted.

2021-10-19drm/amd/display: Do not skip link training on DP quick hot plugJimmy Kizito
[Why] When rapidly plugging and unplugging a DP sink, detection link training can be mistakenly skipped. This is due to the hotplug processing occurring before the encoder assignment logic has had a chance to process the removal of a stream. The encoder that would be used for detection link training is then erroneously reported as already in use and detection link training is skipped. [How] During hot plug processing, only determine a link encoder to be unavailable for a particular link if it has been assigned to a different link.
