2021-08-27Revert "mmc: sdhci-iproc: Set SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN on BCM2711"Ulf Hansson1-2/+1
This reverts commit 419dd626e357e89fc9c4e3863592c8b38cfe1571. It turned out that the change from the reverted commit breaks the ACPI based rpi's because it causes the 100Mhz max clock to be overridden to the return from sdhci_iproc_get_max_clock(), which is 0 because there isn't a OF/DT based clock device.

2021-08-27usb: gadget: f_uac2: fixup feedback endpoint stopJerome Brunet1-4/+11
When the uac2 function is stopped, there seems to be an issue reported on some platforms (Intel Merrifield at least) BUG: kernel NULL pointer dereference, address: 0000000000000008 ... RIP: 0010:dwc3_gadget_del_and_unmap_request+0x19/0xe0 ... Call Trace: dwc3_remove_requests.constprop.0+0x12f/0x170 __dwc3_gadget_ep_disable+0x7a/0x160 dwc3_gadget_ep_disable+0x3d/0xd0 usb_ep_disable+0x1c/0x70 u_audio_stop_capture+0x79/0x120 [u_audio] afunc_set_alt+0x73/0x80 [usb_f_uac2] composite_setup+0x224/0x1b90 [libcomposite] The issue happens only when the gadget is using the sync type "async", not "adaptive". This indicates that problem is coming from the feedback endpoint, which is only used with async synchronization mode. The problem is that request is freed regardless of usb_ep_dequeue(), which ends up badly if the request is not actually dequeued yet. Update the feedback endpoint free function to release the endpoint the same way it is done for the data endpoint, which takes care of the problem.

2021-08-26Revert "block/mq-deadline: Prioritize high-priority requests"Jens Axboe1-37/+5
This reverts commit fb926032b3209300f9dc454a36b8299582ae545c. Zhen reports that this commit slows down mq-deadline on a 128 thread box, going from 258K IOPS to 170-180K. My testing shows that Optane gen2 IOPS goes from 2.3M IOPS to 1.2M IOPS on a 64 thread box. Looking in detail at the code, the main culprit here is needing to sum percpu counters in the dispatch hot path, leading to very high CPU utilization there. To make matters worse, the code currently needs to sum 2 percpu counters, and it does so in the most naive way of iterating possible CPUs _twice_. Since we're close to release, revert this commit and we can re-do it with regular per-priority counters instead for the 5.15 kernel.

2021-08-26Revert "net: really fix the build..."Kalle Valo6-30/+8
This reverts commit ce78ffa3ef1681065ba451cfd545da6126f5ca88. Wren and Nicolas reported that ath11k was failing to initialise QCA6390 Wi-Fi 6 device with error: qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22 Commit ce78ffa3ef16 ("net: really fix the build..."), introduced in v5.14-rc5, caused this regression in qrtr. Most likely all ath11k devices are broken, but I only tested QCA6390. Let's revert the broken commit so that ath11k works again.

2021-08-26sched: Fix get_push_task() vs migrate_disable()Sebastian Andrzej Siewior1-0/+3
push_rt_task() attempts to move the currently running task away if the next runnable task has migration disabled and therefore is pinned on the current CPU. The current task is retrieved via get_push_task() which only checks for nr_cpus_allowed == 1, but does not check whether the task has migration disabled and therefore cannot be moved either. The consequence is a pointless invocation of the migration thread which correctly observes that the task cannot be moved. Return NULL if the task has migration disabled and cannot be moved to another CPU.

The commit 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") moved adev assignment outside of error path and hence made acpi_dev_put(sensor->adev) a no-op.

2021-08-26net: hns3: fix get wrong pfc_en when query PFC configurationGuangbin Huang1-11/+2
Currently, when query PFC configuration by dcbtool, driver will return PFC enable status based on TC. As all priorities are mapped to TC0 by default, if TC0 is enabled, then all priorities mapped to TC0 will be shown as enabled status when query PFC setting, even though some priorities have never been set. for example: $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off $ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on To fix this problem, just returns user's PFC config parameter saved in driver.

In bond 4, when the link goes down and up repeatedly, the bond may get an unknown speed, and then this port can not work. The driver notify netif_carrier_on() before update the link state, when the bond receive carrier on, will query the speed of the port, if the query operation happens before updating the link state, will get an unknown speed. So need to notify netif_carrier_on() after update the link state.

2021-08-26usb: typec: tcpm: Raise vdm_sm_running flag only when VDM SM is runningKyle Tso1-43/+38
If the port is going to send Discover_Identity Message, vdm_sm_running flag was intentionally set before entering Ready States in order to avoid the conflict because the port and the port partner might start AMS at almost the same time after entering Ready States. However, the original design has a problem. When the port is doing DR_SWAP from Device to Host, it raises the flag. Later in the tcpm_send_discover_work, the flag blocks the procedure of sending the Discover_Identity and it might never be cleared until disconnection. Since there exists another flag send_discover representing that the port is going to send Discover_Identity or not, it is enough to use that flag to prevent the conflict. Also change the timing of the set/clear of vdm_sm_running to indicate whether the VDM SM is actually running or not.

2021-08-26usb: renesas-xhci: Prefer firmware loading on unknown ROM stateTakashi Iwai1-12/+23
The recent attempt to handle an unknown ROM state in the commit d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state") resulted in a regression and reverted later by the commit 44cf53602f5a ("Revert "usb: renesas-xhci: Fix handling of unknown ROM state""). The problem of the former fix was that it treated the failure of firmware loading as a fatal error. Since the firmware files aren't included in the standard linux-firmware tree, most users don't have them, hence they got the non-working system after that. The revert fixed the regression, but also it didn't make the firmware loading triggered even on the devices that do need it. So we need still a fix for them. This is another attempt to handle the unknown ROM state. Like the previous fix, this also tries to load the firmware when ROM shows unknown state. In this patch, however, the failure of a firmware loading (such as a missing firmware file) isn't handled as a fatal error any longer when ROM has been already detected, but it falls back to the ROM mode like before. The error is returned only when no ROM is detected and the firmware loading failed. Along with it, for simplifying the code flow, the detection and the check of ROM is factored out from renesas_fw_check_running() and done in the caller side, renesas_xhci_check_request_fw(). It avoids the redundant ROM checks. The patch was tested on Lenovo Thinkpad T14 gen (BIOS 1.34). Also it was confirmed that no regression is seen on another Thinkpad T14 machine that has worked without the patch, too.
