2021-02-08brcmfmac: Add DMI nvram filename quirk for Voyo winpad A15 tabletHans de Goede
The Voyo winpad A15 tablet contains quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt as nvram file which is a bit too generic. Add a DMI quirk so that a unique and clearly identifiable nvram file name is used on the Voyo winpad A15 tablet. While preparing a matching linux-firmware update I noticed that the nvram is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI quirk entry simply points to the already existing Prowise-PT301 nvram file.

2021-02-08rtlwifi: use tasklet_setup to initialize rx_work_taskletEmil Renner Berthing
In commit d3ccc14dfe95 most of the tasklets in this driver was updated to the new API. However for the rx_work_tasklet only the type of the callback was changed from void _rtl_rx_work(unsigned long data) to void _rtl_rx_work(struct tasklet_struct *t). The initialization of rx_work_tasklet was still open-coded and the function pointer just cast into the old type, and hence nothing sets rx_work_tasklet.use_callback = true and the callback was still called as t->func(t->data); with uninitialized/zero t->data. Commit 6b8c7574a5f8 changed the casting of _rtl_rx_work a bit and initialized t->data to a pointer to the tasklet cast to an unsigned long. This way calling t->func(t->data) might actually work through all the casting, but it still doesn't update the code to use the new tasklet API. Let's use the new tasklet_setup to initialize rx_work_tasklet properly and set rx_work_tasklet.use_callback = true so that the callback is called as t->callback(t); without all the casting.

2021-02-08USB: serial: option: update interface mapping for ZTE P685MLech Perczak
This patch prepares for qmi_wwan driver support for the device. Previously "option" driver mapped itself to interfaces 0 and 3 (matching ff/ff/ff), while interface 3 is in fact a QMI port. Interfaces 1 and 2 (matching ff/00/00) expose AT commands, and weren't supported previously at all. Without this patch, a possible conflict would exist if device ID was added to qmi_wwan driver for interface 3. Update and simplify device ID to match interfaces 0-2 directly, to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict with QMI (3), and ADB (4). The modem is used inside ZTE MF283+ router and carriers identify it as such. Interface mapping is: 0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB T: Bus=02 Lev=02 Prnt=02 Port=05 Cnt=01 Dev#= 3 Spd=480 MxCh= 0 D: Ver= 2.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=19d2 ProdID=1275 Rev=f0.00 S: Manufacturer=ZTE,Incorporated S: Product=ZTE Technologies MSM S: SerialNumber=P685M510ZTED0000CP&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&0 C:* #Ifs= 5 Cfg#= 1 Atr=a0 MxPwr=500mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

2021-02-07watchdog: mei_wdt: request stop on unregisterAlexander Usyskin
The MEI bus has a special behavior on suspend it destroys all the attached devices, this is due to the fact that also firmware context is not persistent across power flows. If watchdog on MEI bus is ticking before suspending the firmware times out and reports that the OS is missing watchdog tick. Send the stop command to the firmware on watchdog unregistered to eliminate the false event on suspend. This does not make the things worse from the user-space perspective as a user-space should re-open watchdog device after suspending before this patch.

2021-02-07soundwire: bus: clarify dev_err/dbg device referencesPierre-Louis Bossart
The SoundWire bus code confuses bus and Slave device levels for dev_err/dbg logs. That's not impacting functionality but the accuracy of kernel logs. We should only use bus->dev for bus-level operations and handling of Device0. For all other logs where the device number is not zero, we should use &slave->dev to provide more precisions to the user/integrator.

2021-02-07soundwire: bus: fix confusion on device used by pm_runtimePierre-Louis Bossart
Intel stress-tests routinely report IO timeouts and invalid power management transitions. Upon further analysis, we seem to be using the wrong devices in pm_runtime calls. Before reading and writing registers, we first need to make sure the Slave is fully resumed. The existing code attempts to do such that, however because of a confusion dating from 2017 and copy/paste, we end-up resuming the parent only instead of resuming the codec device. This can lead to accesses to the Slave registers while the bus is still being configured and the Slave not enumerated, and as a result IO errors occur. This is a classic problem, similar confusions happened for HDaudio between bus and codec device, leading to power management issues. Fix by using the relevant device for all uses of pm_runtime functions.

The global gpio_desc pointer and int vbus_irq were defined in the header, instead put the definitions in the translation unit and make them static as there's only a single consumer, and these symbols shouldn't pollute the global namespace.

2021-02-06net: ipa: avoid field overflowAlex Elder
It's possible that the length passed to ipa_header_size_encoded() is larger than what can be represented by the HDR_LEN field alone (starting with IPA v4.5). If we attempted that, u32_encode_bits() would trigger a build-time error. Avoid this problem by masking off high-order bits of the value encoded as the lower portion of the header length. The same sort of problem exists in ipa_metadata_offset_encoded(), so implement the same fix there. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-02-06net: ipa: do not cache event ring stateAlex Elder
An event ring's state only needs to be known when it is allocated, reset, or deallocated. We check an event ring's state both before and after performing an event ring control command that changes its state. These are only issued at startup and shutdown, so there is very little value in caching the state. Stop recording a copy of the channel's last known state, and instead fetch the true state from hardware whenever it's needed. In such cases, *do* record the state in a local variable, in case an error message reports it (so the value reported is the value seen).
