2024-07-12Input: yealink - simplify locking in sysfs attribute handlingDmitry Torokhov
The locking rules in the driver came from era when sysfs attributes could live past the point of time when device would be unbound from the driver, and so used module-global semaphore (potentially shared between multiple yealink devices). Thankfully these times are long gone and attributes will not be accessible once they are removed. Simplify the logic by moving to per-device mutex, stop checking if there is driver data instance attached to the interface, and use guard notation to acquire the mutex.

2024-05-13Input: drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

2024-01-01Input: iqs269a - add support for OTP variantsJeff LaBundy
This patch adds support for each available OTP variant of the device. The OTP configuration cannot be read over I2C, so it is derived from a compatible string instead. Early revisions of the D0 order code require their OTP-enabled func- tionality to be manually restored following a soft reset; this patch accommodates this erratum as well.

2024-01-01Input: iqs269a - add support for slider gesturesJeff LaBundy
This patch adds support for slider gestures that can be expressed by the device. Each gesture (e.g. tap or hold) can be mapped to a unique keycode for either slider 0 or 1. With this change, raw slider coordinates are reported only if the slider has no keycodes defined. This prevents unwanted mouse cur- sor movement when expressing axial gestures (e.g. swipe) and also eliminates some unnecessary I2C traffic. Different revisions of silicon use different tap and swipe timeout step sizes. Apply an appropriate scaling factor depending on which revision is found. To facilitate this change, store the iqs269_ver_info struct in the driver's private data so that other functions can use it after the driver has probed. Last but not least, a former reserved field in iqs269_ver_info now contains useful information; give it a name (fw_num).

2023-12-22Input: soc_button_array - add mapping for airplane mode buttonChristoffer Sandberg
This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3. While it is physically a key it behaves more like a switch, sending a key down on first press and a key up on 2nd press. Therefor the switch event is used here. Besides this behaviour it uses the HID usage-id 0xc6 (Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but since neither 0xc6 nor 0xc8 are currently implemented at all in soc_button_array this not to standard behaviour is not put behind a quirk for the moment.

2023-12-20pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()Sean Young
In order to introduce a pwm api which can be used from atomic context, we will need two functions for applying pwm changes: int pwm_apply_might_sleep(struct pwm *, struct pwm_state *); int pwm_apply_atomic(struct pwm *, struct pwm_state *); This commit just deals with renaming pwm_apply_state(), a following commit will introduce the pwm_apply_atomic() function.

Simplify probe() by replacing of_match_node() for retrieving match data by device_get_match_data(). Some minor cleanups: * Remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing. * Move OF table near to the user. * Arrange variables in reverse xmas tree order in probe().

Add the needed device-tree compatible strings to the MAX77693 haptic driver, so it can be automatically loaded when compiled as a kernel module and given device-tree contains separate (i.e. 'motor-driver') node under the main PMIC node. When device is instantiated from device-tree, the driver data cannot be read via platform_get_device_id(), so get device type from the parent MFD device instead, what works for both cases.

2023-10-13Input: powermate - fix use-after-free in powermate_config_completeJavier Carrasco
syzbot has found a use-after-free bug [1] in the powermate driver. This happens when the device is disconnected, which leads to a memory free from the powermate_device struct. When an asynchronous control message completes after the kfree and its callback is invoked, the lock does not exist anymore and hence the bug. Use usb_kill_urb() on pm->config to cancel any in-progress requests upon device disconnection.

This code is doing more work than it needs to. Before handing off `val_str` to `kstrtouint()` we are eagerly removing any trailing newline which requires copying `buf`, validating it's length and checking/replacing any potential newlines. kstrtouint() handles this implicitly: kstrtouint -> kstrotoull -> (documentation) | /** | * kstrtoull - convert a string to an unsigned long long | * @s: The start of the string. The string must be null-terminated, and may also | * include a single newline before its terminating null. The first character | ... Let's remove the redundant functionality and let kstrtouint handle it.
