* HID: intel_ish-hid: Stop using a static local buffer in get_report()Hans de Goede2018-04-251-10/+6
| | | | | | | | | | | | | | hid_ishtp_get_report() may be called by multiple callers at the same time, causing trouble with the static local buffer used. Also there is no reason to use a non stack buffer, the buffer is tiny and ishtp_cl_send() copies its contents so the lifetime is not an issue either.

| | | | | | | | | | | | | | Doing `ioctl(HIDIOCGFEATURE)` in a tight loop on a hidraw device and then disconnecting the device, or unloading the driver, can cause a NULL pointer dereference. When a hidraw device is destroyed it sets 0 to `dev->exist`. Most functions check 'dev->exist' before doing its work, but `hidraw_get_report()` was missing that check.

* HID: input: fix battery level reporting on BT miceDmitry Torokhov2018-04-092-8/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 581c4484769e ("HID: input: map digitizer battery usage") assumed that devices having input (qas opposed to feature) report for battery strength would report the data on their own, without the need to be polled by the kernel; unfortunately it is not so. Many wireless mice do not send unsolicited reports with battery strength data and have to be polled explicitly. As a complication, stylus devices on digitizers are not normally connected to the base and thus can not be polled - the base can only determine battery strength in the stylus when it is in proximity. To solve this issue, we add a special flag that tells the kernel to avoid polling the device (and expect unsolicited reports) and set it when report field with physical usage of digitizer stylus (HID_DG_STYLUS). Unless this flag is set, and we have not seen the unsolicited reports, the kernel will attempt to poll the device when userspace attempts to read "capacity" and "state" attributes of power_supply object corresponding to the devices battery.

The keyboard is already supported by the existing Linux kernel and drivers but the touchpad is not recognized. This patch adds the coded needed to bring full functionality to the touchpad. Note that these remotes use the vendor code for SMK even though they are Sony branded. Known limitations - The built-in accelerometers are not supported by these changes - When the Drag (Fn) key is used as a mouse button, the button is automatically released when the key begins repeating. There are two workarounds for this 1) Use the button behind the touchpad instead of the Drag (Fn) key or 2) Disable the key repeat functionality or increase the key repeat delay.

| | * | HID: elecom: refer to trackballs by model name instead of seriesTomasz Kramkowski2018-03-064-30/+30
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes all references to ELECOM trackballs using their series name to refer to them by their model name. ELECOM provides multiple series of mice such as EX-G, HUGE, and DEFT. Although it has not caused conflicts in the driver, there can be more than one iteration of mice in each series. For example, there are 7 variants of EX-G trackballs but only three (M-XT3URBK, M-XT3DRBK, and M-XT4DRBK) need a driver to work correctly. There are also 4 DEFT series trackballs but two of them have the same VID:PID as the other two. I picked the earlier model for the naming of the PID macros.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | K70 Vengeance sends garbage keypresses when changing backlight brightness. This hooks to the existing corsair driver, which filters out those invalid keypresses on similar devices in the input mapping code. V2: Fix spelling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When size is negative, calling memset will make segment fault. Declare the size as type u32 to keep memset safe. size in struct hid_report is unsigned, fix return type of hid_report_len to u32.
