Input: elantech - add Fujitsu Lifebook E556 to force crc_enabled

2016-10-07T23:30:12+00:00

Another Lifebook machine that needs the same quirk as other similar
models to make the driver working.

Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries
are in alphabetical order.

Input: ALPS - set DualPoint flag for 74 03 28 devices

2016-10-04T18:47:01+00:00

Here we introduce logic in alps_identify to set the ALPS_DUALPOINT flag
for touchpad hardware responding to E7 report with 73 03 28, as is found
in the Dell Latitude E7470.

Input: ALPS - handle 0-pressure 1F events

2016-10-04T18:46:51+00:00

While a button is held SS5 hardware will give us single-finger packets
with x, y, and pressure equal to zero. This causes annoying jumps in
pointer position if a touch is released while the button is held. Handle
this by claiming zero contacts to ensure that no position events are
provided to the user.

Add touchstick support for the so-called SS5 hardware, which uses a
variant of the SS4 protocol.

Input: elantech - force needed quirks on Fujitsu H760

2016-10-04T00:31:57+00:00

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with
the same quirks. Without this patch, the touchpad is useless out-of-the-box
as the mouse pointer won't move.

This patch makes the driver aware of both the crc_enabled=1 requirement and
the middle button, making the touchpad fully functional out-of-the-box.

Input: elan_i2c - fix return tests of i2c_smbus_read_block_data()

2016-10-03T23:41:00+00:00

i2c_smbus_read_block_data() returns negative errno else the number of
data bytes in the slave's response.

Checking for error not null means the function always fails if the device
answers properly.

So given that we read 3 bytes and access those, better check that we
actually read those 3 bytes.

Input: focaltech - mark focaltech_set_resolution() static

2016-09-05T17:42:11+00:00

We get 1 warning when building kernel with W=1:
drivers/input/mouse/focaltech.c:393:6: warning: no previous prototype for 'focaltech_set_resolution' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
So this patch marks it 'static'.

Input: psmouse - remove deprecated create_singletheread_workqueue

2016-08-25T17:10:53+00:00

alloc_ordered_workqueue() replaces the deprecated
create_singlethread_workqueue().

There are multiple work items on the work queue viz
&priv->dev3_register_work, &priv->recalib_wq, &psmouse->resync_work,
which require execution ordering. Hence, an ordered workqueue has been
used.

The workqueue is not being used on a memory reclaim path.  Hence,
WQ_MEM_RECLAIM has not been set.
