2019-11-04Input: synaptics-rmi4 - disable the relative position IRQ in the F12 driverAndrew Duggan1-2/+26
This patch fixes an issue seen on HID touchpads which report finger positions using RMI4 Function 12. The issue manifests itself as spurious button presses as described in: https://www.spinics.net/lists/linux-input/msg58618.html Commit 24d28e4f1271 ("Input: synaptics-rmi4 - convert irq distribution to irq_domain") switched the RMI4 driver to using an irq_domain to handle RMI4 function interrupts. Functions with more then one interrupt now have each interrupt mapped to their own IRQ and IRQ handler. The result of this change is that the F12 IRQ handler was now getting called twice. Once for the absolute data interrupt and once for the relative data interrupt. For HID devices, calling rmi_f12_attention() a second time causes the attn_data data pointer and size to be set incorrectly. When the touchpad button is pressed, F30 will generate an interrupt and attempt to read the F30 data from the invalid attn_data data pointer and report incorrect button events. This patch disables the F12 relative interrupt which prevents rmi_f12_attention() from being called twice.

2019-11-04Input: synaptics-rmi4 - fix video buffer sizeLucas Stach1-1/+1
The video buffer used by the queue is a vb2_v4l2_buffer, not a plain vb2_buffer. Using the wrong type causes the allocation of the buffer storage to be too small, causing a out of bounds write when __init_vb2_v4l2_buffer initializes the buffer.

2019-10-29Input: kxtj9 - switch to using polled mode of input devicesDmitry Torokhov2-122/+37
We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts kxtj9 driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. note that with regular input devices handling polling, there is no longer a benefit in having separate INPUT_KXTJ9_POLLED_MODE config option.
