Input: twl4030-vibra - fix sibling-node lookup

2018-01-23T18:57:07+00:00

commit 5b189201993ab03001a398de731045bfea90c689 upstream.

A helper purported to look up a child node based on its name was using
the wrong of-helper and ended up prematurely freeing the parent of-node
while searching the whole device tree depth-first starting at the parent
node.

Input: twl6040-vibra - fix child-node lookup

2018-01-23T18:57:07+00:00

commit dcaf12a8b0bbdbfcfa2be8dff2c4948d9844b4ad upstream.

Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at parent rather than just matching on
its children.

Later sanity checks on node properties (which would likely be missing)
should prevent this from causing much trouble however, especially as the
original premature free of the parent node has already been fixed
separately (but that "fix" was apparently never backported to stable).

Input: ims-psu - check if CDC union descriptor is sane

2017-11-18T10:22:24+00:00

commit ea04efee7635c9120d015dcdeeeb6988130cb67a upstream.

Before trying to use CDC union descriptor, try to validate whether that it
is sane by checking that intf->altsetting->extra is big enough and that
descriptor bLength is not too big and not too small.

Input: uinput - fix crash when mixing old and new init style

2017-02-14T23:25:34+00:00

commit 601bbbe0517303c9f8eb3d75e11d64efed1293c9 upstream.

If user tries to initialize uinput device mixing old and new style
initialization (i.e. using old UI_SET_ABSBIT instead of UI_ABS_SETUP,
we forget to allocate input->absinfo and will crash when trying to send
absolute events:

        ioctl(ui, UI_DEV_SETUP, &us);
        ioctl(ui, UI_SET_PHYS, "Test");

        ioctl(ui, UI_SET_EVBIT, EV_ABS);
        ioctl(ui, UI_SET_ABSBIT, ABS_X);
        ioctl(ui, UI_SET_ABSBIT, ABS_Y);
        ioctl(ui, UI_DEV_CREATE, 0);

Input: drv260x - fix input device's parent assignment

2017-01-09T07:32:24+00:00

commit 5a8a6b89c15766446d845671d574a9243b6d8786 upstream.

We were assigning I2C bus controller instead of client as parent device.
Besides being logically wrong, it messed up with devm handling of input
device. As a result we were leaving input device and event node behind
after rmmod-ing the driver, which lead to a kernel oops if one were to
access the event node later.

Let's remove the assignment and rely on devm_input_allocate_device() to
set it up properly for us.

Pull input subsystem updates from Dmitry Torokhov:
 "You will get

   - a new driver for Elan eKTF2127 touchscreen controllers

   - a new "gpio-decoder" driver to read and report state of several
     GPIO lines

   - an ADC resistor ladder driver

   - the ft6326 driver is removed because edt-ft5x06 handles the same
     devices just fine.

  .. plus the regular slew of driver fixes/enhancements"

Input: tps65218-pwrbutton - add support for tps65217 variant

2016-09-10T17:47:49+00:00

The power button found in tps65217 device is very similar to the tps65218,
so let's enhance the driver to support both variants.

This driver enables us to use tps65217's power button as KEY_POWER on
am335x boards (directly connected button in chiliboard, accessible pin
via expansion header in beaglebone). This patch has been tested with
chiliboard.
