 "A fix (revert) for a recent regression in Synaptics driver and a fix
  for Elan i2c touchpad driver"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:

Revert "Input: synaptics - allocate 3 slots to keep stability in image sensors"

2015-07-10T17:11:07+00:00

This reverts commit 63c4fda3c0bb841b1aad1298fc7fe94058fc79f8 as it
causes issues with detecting 3-finger taps.

Input: elan_i2c - change the hover event from MT to ST

2015-07-07T18:28:31+00:00

The firmware only reports hover condition while the very first contact is
approaching the surface; the hover is not reported for the subsequent
contacts. Therefore we should not be using ABS_MT_DISTANCE to report hover
but rather its single-touch counterpart ABS_DISTANCE.

Pull module updates from Rusty Russell:
 "Main excitement here is Peter Zijlstra's lockless rbtree optimization
  to speed module address lookup.  He found some abusers of the module
  lock doing that too.

  A little bit of parameter work here too; including Dan Streetman's
  breaking up the big param mutex so writing a parameter can load
  another module (yeah, really).  Unfortunately that broke the usual
  suspects, !CONFIG_MODULES and !CONFIG_SYSFS, so those fixes were
  appended too"

  modules: only use mod->param_lock if CONFIG_MODULES
  param: fix module param locks when !CONFIG_SYSFS.
  rcu: merge fix for Convert ACCESS_ONCE() to READ_ONCE() and WRITE_ONCE()
  module: add per-module param_lock
  module: make perm const
  params: suppress unused variable error, warn once just in case code changes.

Merge branch 'next' into for-linus

2015-06-22T16:26:29+00:00

Prepare first round of input updates for 4.2 merge window.

Input: elan_i2c - add product IDs FW names

2015-06-09T00:12:25+00:00

Previously the elan_i2c touchpad driver would simply request the firmware
"/lib/firmware/elan_i2c.bin", which does not work well if there are
multiple such devices in the system.

Let's append the "product ID" (by using the same function as the sysfs
interface for consistency) to the filename.  This results in filenames of
the form "/lib/firmware/elan_i2c_72.0.bin", allowing you to support
multiple elan_i2c touchpads on the same device by simply naming each
device's FW with its corresponding product ID.  This way when you trigger a
fw update the driver will load the correct binary.

Input: elan_i2c - add support for multi IC type and iap format

2015-06-09T00:12:24+00:00

In order to support multiple IC types for i2c/smbus protocol, add get ic
type command and use this data when checking firmware page count and
signature address.

Input: alps - do not reduce trackpoint speed by half

2015-06-05T05:34:40+00:00

On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically
only in the 0-1 range dividing this by 2 results in a range of 0-0.

And even for v7 devices where this does not lead to making the trackstick
entirely unusable, it makes it twice as slow as before we added v7 support
and were using the ps/2 mouse emulation of the dual point setup.

If some kind of generic slowdown is actually necessary for some devices,
then that belongs in userspace, not in the kernel.
