2020-10-05platform/x86: thinkpad_acpi: re-initialize ACPI buffer size when reuseAaron Ma
Evaluating ACPI _BCL could fail, then ACPI buffer size will be set to 0. When reuse this ACPI buffer, AE_BUFFER_OVERFLOW will be triggered. Re-initialize buffer size will make ACPI evaluate successfully.

2020-10-05mmc: sdhci-acpi: AMDI0040: Set SDHCI_QUIRK2_PRESET_VALUE_BROKENRaul E Rangel
This change fixes HS400 tuning for devices with invalid presets. SDHCI presets are not currently used for eMMC HS/HS200/HS400, but are used for DDR52. The HS400 retuning sequence is: HS400->DDR52->HS->HS200->Perform Tuning->HS->HS400 This means that when HS400 tuning happens, we transition through DDR52 for a very brief period. This causes presets to be enabled unintentionally and stay enabled when transitioning back to HS200 or HS400. Some firmware has invalid presets, so we end up with driver strengths that can cause I/O problems.

2020-10-04net: team: fix memory leak in __team_options_registerAnant Thazhemadam
The variable "i" isn't initialized back correctly after the first loop under the label inst_rollback gets executed. The value of "i" is assigned to be option_count - 1, and the ensuing loop (under alloc_rollback) begins by initializing i--. Thus, the value of i when the loop begins execution will now become i = option_count - 2. Thus, when kfree(dst_opts[i]) is called in the second loop in this order, (i.e., inst_rollback followed by alloc_rollback), dst_optsp[option_count - 2] is the first element freed, and dst_opts[option_count - 1] does not get freed, and thus, a memory leak is caused. This memory leak can be fixed, by assigning i = option_count (instead of option_count - 1).

2020-10-04hwmon: (bt1-pvt) Wait for the completion with timeoutSerge Semin
If the PVT sensor is suddenly powered down while a caller is waiting for the conversion completion, the request won't be finished and the task will hang up on this procedure until the power is back up again. Let's call the wait_for_completion_timeout() method instead to prevent that. The cached timeout is exactly what we need to predict for how long conversion could normally last.

2020-10-04hwmon: (bt1-pvt) Cache current update timeoutSerge Semin
Instead of converting the update timeout data to the milliseconds each time on the read procedure let's preserve the currently set timeout in the dedicated driver private data cache. The cached value will be then used in the timeout read method and in the alarm-less data conversion to prevent the caller task hanging up in case if the PVT sensor is suddenly powered down.

2020-10-04hwmon: (bt1-pvt) Test sensor power supply on probeSerge Semin
Baikal-T1 PVT sensor has got a dedicated power supply domain (feed up by the external GPVT/VPVT_18 pins). In case if it isn't powered up, the registers will be accessible, but the sensor conversion just won't happen. Due to that an attempt to read data from any PVT sensor will cause the task hanging up. For instance that will happen if XP11 jumper isn't installed on the Baikal-T1-based BFK3.1 board. Let's at least test whether the conversion work on the device probe procedure. By doing so will make sure that the PVT sensor is powered up at least at boot time.

2020-10-04hwmon: Add hwmon driver for Intel MAX 10 BMCXu Yilun
This patch adds hwmon functionality for Intel MAX 10 BMC chip. This BMC chip connects to a set of sensor chips to monitor current, voltage, thermal and power of different components on board. The BMC firmware is responsible for sensor data sampling and recording in shared registers. Host driver reads the sensor data from these shared registers and exposes them to users as hwmon interfaces.

2020-10-04vhost-vdpa: fix page pinning leakage in error pathSi-Wei Liu
Pinned pages are not properly accounted particularly when mapping error occurs on IOTLB update. Clean up dangling pinned pages for the error path. As the inflight pinned pages, specifically for memory region that strides across multiple chunks, would need more than one free page for book keeping and accounting. For simplicity, pin pages for all memory in the IOVA range in one go rather than have multiple pin_user_pages calls to make up the entire region. This way it's easier to track and account the pages already mapped, particularly for clean-up in the error path.
