Input: hyperv-keyboard: Use in-place iterator API in the channel callback

2019-08-20T15:28:04Z

Simplify the ring buffer handling with the in-place API. Also avoid the dynamic allocation and the memory leak in the channel callback function. Signed-off-by: Dexuan Cui Acked-by: Dmitry Torokhov Signed-off-by: Sasha Levin

Input: iforce - add sanity checks

2019-08-06T16:10:57Z

The endpoint type should also be checked before a device is accepted. Reported-by: syzbot+5efc10c005014d061a74@syzkaller.appspotmail.com Signed-off-by: Oliver Neukum Signed-off-by: Dmitry Torokhov

Input: applespi - use struct_size() helper

2019-08-06T16:10:56Z

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct touchpad_protocol { ... struct tp_finger fingers[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*tp) + tp->number_of_fingers * sizeof(tp->fingers[0]); with: struct_size(tp, fingers, tp->number_of_fingers) This code was detected with the help of Coccinelle.

Input: kbtab - sanity check for endpoint type

2019-08-01T17:55:21Z

The driver should check whether the endpoint it uses has the correct type. Reported-by: syzbot+c7df50363aaff50aa363@syzkaller.appspotmail.com Signed-off-by: Oliver Neukum Signed-off-by: Dmitry Torokhov

Input: usbtouchscreen - initialize PM mutex before using it

2019-08-01T17:55:20Z

Mutexes shall be initialized before they are used. Fixes: 12e510dbc57b2 ("Input: usbtouchscreen - fix deadlock in autosuspend") Reported-by: syzbot+199ea16c7f26418b4365@syzkaller.appspotmail.com Signed-off-by: Oliver Neukum Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

Input: applespi - add dependency on LEDS_CLASS

2019-07-31T13:50:18Z

If applespi is enabled, but LEDs class support is not, the build fails: drivers/input/keyboard/applespi.o: In function `applespi_probe': applespi.c:(.text+0x1fcd): undefined reference to `devm_led_classdev_register_ext' Add "depends on LEDS_CLASS" to the Konfig Reported-by: Hulk Robot Fixes: 038b1a05eae6 ("Input: add Apple SPI keyboard and trackpad driver") Signed-off-by: YueHaibing Signed-off-by: Dmitry Torokhov

Input: synaptics - enable RMI mode for HP Spectre X360

2019-07-25T08:24:06Z

The 2016 kabylake HP Spectre X360 (model number 13-w013dx) works much better with psmouse.synaptics_intertouch=1 kernel parameter, so let's enable RMI4 mode automatically.

Input: elantech - annotate fall-through case in elantech_use_host_notify()

2019-07-24T09:43:51Z

This avoids a warning when building with -Wimplicit-fallthrough. Fixes: 883a2a80f79c ("Input: elantech - enable SMBus on new (2018+) systems") Reported-by: Stephen Rothwell Signed-off-by: Dmitry Torokhov

Input: elantech - enable SMBus on new (2018+) systems

2019-07-23T13:49:22Z

There are some new HP laptops with Elantech touchpad that don't support multitouch. Currently we use ETP_NEW_IC_SMBUS_HOST_NOTIFY() to check if SMBus is supported, but in addition to firmware version, the bus type also informs us whether the IC can support SMBus. To avoid breaking old ICs, we will only enable SMbus support based the bus type on systems manufactured after 2018. Lastly, let's consolidate all checks into elantech_use_host_notify() and use it to determine whether to use PS/2 or SMBus.
