2025-01-09HID: hid-steam: Make sure rumble work is canceled on removalVicki Pfau
When a force feedback command is sent from userspace, work is scheduled to pass this data to the controller without blocking userspace itself. However, in theory, this work might not be properly canceled if the controller is removed at the exact right time. This patch ensures the work is properly canceled when the device is removed.

2025-01-09HID: intel-thc-hid: intel-thc: Add THC DMA interfacesEven Xu
As THC PIO only has 64 bytes FIFO length, THC DMAs are introduced to send/receive large data packets. THC has three types of DMA channels: Read DMA channel (RxDMA), Write DMA channel (TxDMA) and Software DMA (SWDMA). In addition to basic DMA functions, THC RxDMA also includes an auto hardware sequence which can handle external touch device's interrupt automatically without software involved. THC RxDMA channel usually is used for handling touch input reports. THC TxDMA is very similar with general IO TxDMA, and usually is used for sending command/request to exteranl touch device. THC SWDMA can perform read, write followed by read operation according to different configurations. Unlike RxDMA triggered by bus activity, SWDMA can be triggered by SW driver at any time, for example: - Retrieving an input report without interrupt - Sending command followed by reading response THC DMA operation flow includes 4 steps: 1. Allocate DMA buffers 2. Configure opcode, fill PRD table with DMA buffers, enable DMA channel 3. Wait for completion, read out DMA buffers and update buffer pointers 4. Stop DMA and release DMA buffers THC Hardware layer driver provides APIs for all above DMA Steps.

2025-01-09HID: core: Fix assumption that Resolution Multipliers must be in Logical ↵Alan Stern
Collections A report in 2019 by the syzbot fuzzer was found to be connected to two errors in the HID core associated with Resolution Multipliers. One of the errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloop in hid_apply_multiplier."), but the other has not been fixed. This error arises because hid_apply_multipler() assumes that every Resolution Multiplier control is contained in a Logical Collection, i.e., there's no way the routine can ever set multiplier_collection to NULL. This is in spite of the fact that the function starts with a big comment saying: * "The Resolution Multiplier control must be contained in the same * Logical Collection as the control(s) to which it is to be applied. ... * If no Logical Collection is * defined, the Resolution Multiplier is associated with all * controls in the report." * HID Usage Table, v1.12, Section 4.3.1, p30 * * Thus, search from the current collection upwards until we find a * logical collection... The comment and the code overlook the possibility that none of the collections found may be a Logical Collection. The fix is to set the multiplier_collection pointer to NULL if the collection found isn't a Logical Collection.

2025-01-09HID: wacom: Status luminance properties should set brightness of all LEDsJason Gerecke
The wacom driver has (deprecated) sysfs properties `status0_luminance` and `status1_luminance` that are used to control the low- and high- level brightness values (llv and hlv) of the status LEDs. These two properties had an effect on /all/ of the status LEDs. After our driver switched to exposing each status LED individually through the LED class, this behavior changed. These controls started having only a temporary effect on the currently-lit LED. If a trigger changed the current LED, the driver would switch the brightness back to the llv/hlv values stored per-LED. (The code's current behavior of updating the "global" e.g. `wacom->led.llv` values has essentially no effect because those values are only used at initialization time). This commit restores the original behavior by ensuring these properties update the per-LED brightness for all LEDs.

2025-01-09HID: wacom: Improve behavior of non-standard LED brightness valuesJason Gerecke
Assigning a non-standard brightness value to an LED can cause the value to slowly drift downward over time as the effects of integer division accumulate. Each time that an LED is triggered, a series of set and get calls occur. For example, if we assume a tablet with max_hlv = 100, then when brightness is set to "200" through sysfs, the hlv value written to hardware will be `200*100/255 = 78`. If the LED trigger is later activated, the hlv value will be used to determine the brightness: `78*255/100 = 198`. This lower brightness then used to set the brightness of the next LED. However, `198*100/255 = 77`, so the next LED ends up slightly dimmer. Each subsequent trigger activation will cause the brightness to continue drifting down until we reach a point where the result of integer divsion does not introduce any new error. This commit corrects the issue by being more careful about how we handle scaling between the two ranges (0..max_{h,l}lv) and (0..LED_FULL).

2025-01-09fbdev: omapfb: Fix an OF node leak in dss_of_port_get_parent_device()Joe Hattori
dss_of_port_get_parent_device() leaks an OF node reference when i >= 2 and struct device_node *np is present. Since of_get_next_parent() obtains a reference of the returned OF node, call of_node_put() before returning NULL. This was found by an experimental verifier that I am developing, and no runtime test was able to be performed due to that lack of actual devices.

2025-01-08firmware: qcom: scm: add calls for wrapped key supportGaurav Kashyap
Add helper functions for the SCM calls required to support hardware-wrapped inline storage encryption keys. These SCM calls manage wrapped keys via Qualcomm's Hardware Key Manager (HWKM), which can only be accessed from TrustZone. QCOM_SCM_ES_GENERATE_ICE_KEY and QCOM_SCM_ES_IMPORT_ICE_KEY create a new long-term wrapped key, with the former making the hardware generate the key and the latter importing a raw key. QCOM_SCM_ES_PREPARE_ICE_KEY converts the key to ephemerally-wrapped form so that it can be used for inline storage encryption. These are planned to be wired up to new ioctls via the blk-crypto framework; see the proposed documentation for the hardware-wrapped keys feature for more information. Similarly there's also QCOM_SCM_ES_DERIVE_SW_SECRET which derives a "software secret" from an ephemerally-wrapped key and will be wired up to the corresponding operation in the blk_crypto_profile. These will all be used by the ICE driver in drivers/soc/qcom/ice.c. [EB: merged related patches, fixed error handling, fixed naming, fixed docs for size parameters, fixed qcom_scm_has_wrapped_key_support(), improved comments, improved commit message.] Signed-off-by: Gaurav Kashyap <quic_gaurkash@quicinc.com> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> Signed-off-by: Eric Biggers <ebiggers@google.com> Link: https://lore.kernel.org/r/20241213041958.202565-9-ebiggers@kernel.org Signed-off-by: Bjorn Andersson <andersson@kernel.org>
