2020-08-27drm/amd/pm: avoid false alarm due to confusing softwareshutdowntemp settingEvan Quan
Normally softwareshutdowntemp should be greater than Thotspotlimit. However, on some VEGA10 ASIC, the softwareshutdowntemp is 91C while Thotspotlimit is 105C.

2020-08-27RDMA/bnxt_re: Remove the qp from list only if the qp destroy succeedsSelvin Xavier
Driver crashes when destroy_qp is re-tried because of an error returned. This is because the qp entry was removed from the qp list during the first call. Remove qp from the list only if destroy_qp returns success. The driver will still trigger a WARN_ON due to the memory leaking, but at least it isn't corrupting memory too.

2020-08-27RDMA/bnxt_re: Fix driver crash on unaligned PSN entry addressNaresh Kumar PBS
When computing the first psn entry, driver checks for page alignment. If this address is not page aligned,it attempts to compute the offset in that page for later use by using ALIGN macro. ALIGN macro does not return offset bytes but the requested aligned address and hence cannot be used directly to store as offset. Since driver was using the address itself instead of offset, it resulted in invalid address when filling the psn buffer. Fixed driver to use PAGE_MASK macro to calculate the offset.

The Sound Devices MixPre-D audio card suffers from the same defect as the Sound Devices USBPre2: an endpoint shared between a normal audio interface and a vendor-specific interface, in violation of the USB spec. Since the USB core now treats duplicated endpoints as bugs and ignores them, the audio endpoint isn't available and the card can't be used for audio capture. Along the same lines as commit bdd1b147b802 ("USB: quirks: blacklist duplicate ep on Sound Devices USBPre2"), this patch adds a quirks entry saying to ignore ep5in for interface 1, leaving it available for use with standard audio interface 2.

2020-08-27XEN uses irqdesc::irq_data_common::handler_data to store a per interruptThomas Gleixner
XEN data pointer which contains XEN specific information. handler data is meant for interrupt handlers and not for storing irq chip specific information as some devices require handler data to store internal per interrupt information, e.g. pinctrl/GPIO chained interrupt handlers. This obviously creates a conflict of interests and crashes the machine because the XEN pointer is overwritten by the driver pointer. As the XEN data is not handler specific it should be stored in irqdesc::irq_data::chip_data instead. A simple sed s/irq_[sg]et_handler_data/irq_[sg]et_chip_data/ cures that.

2020-08-26drivers/net/wan/lapbether: Set network_header before transmittingXie He
Set the skb's network_header before it is passed to the underlying Ethernet device for transmission. This patch fixes the following issue: When we use this driver with AF_PACKET sockets, there would be error messages of: protocol 0805 is buggy, dev (Ethernet interface name) printed in the system "dmesg" log. This is because skbs passed down to the Ethernet device for transmission don't have their network_header properly set, and the dev_queue_xmit_nit function in net/core/dev.c complains about this. Reason of setting the network_header to this place (at the end of the Ethernet header, and at the beginning of the Ethernet payload): Because when this driver receives an skb from the Ethernet device, the network_header is also set at this place.

2020-08-26drm/amd/display: Retry AUX write when fail occursWayne Lin
[Why] In dm_dp_aux_transfer() now, we forget to handle AUX_WR fail cases. We suppose every write wil get done successfully and hence some AUX commands might not sent out indeed. [How] Check if AUX_WR success. If not, retry it.

2020-08-26drm/amdgpu: Fix buffer overflow in INFO ioctlAlex Deucher
The values for "se_num" and "sh_num" come from the user in the ioctl. They can be in the 0-255 range but if they're more than AMDGPU_GFX_MAX_SE (4) or AMDGPU_GFX_MAX_SH_PER_SE (2) then it results in an out of bounds read.

2020-08-26drm/amd/powerplay: Fix hardmins not being sent to SMU for RVNicholas Kazlauskas
[Why] DC uses these to raise the voltage as needed for higher dispclk/dppclk and to ensure that we have enough bandwidth to drive the displays. There's a bug preventing these from actuially sending messages since it's checking the actual clock (which is 0) instead of the incoming clock (which shouldn't be 0) when deciding to send the hardmin. [How] Check the clocks != 0 instead of the actual clocks.
