Input: elan_i2c - properly wake up touchpad on ASUS laptops

2016-08-20T16:09:26+00:00

commit 2de4fcc64685def3e586856a2dc636df44532395 upstream.

Some ASUS laptops were shipped with touchpads that require to be woken up
first, before trying to switch them into absolute reporting mode, otherwise
touchpad would fail to work while flooding the logs with:

	elan_i2c i2c-ELAN1000:00: invalid report id data (1)

Among affected devices are Asus E202SA, N552VW, X456UF, UX305CA, and
others. We detect such devices by checking the IC type and product ID
numbers and adjusting order of operations accordingly.

sur40: fix occasional oopses on device close

2016-08-20T16:09:19+00:00

commit 6a8588156657e607fcfdffd46c1daae8ba88a1e5 upstream.

Closing the V4L2 device sometimes triggers a kernel oops.
Present patch fixes this.

sur40: lower poll interval to fix occasional FPS drops to ~56 FPS

2016-08-20T16:09:18+00:00

commit af766ee005c496b8567976dc3eed7676443ed6de upstream.

The framerate sometimes drops below 60 Hz if the poll interval is too high.
Lowering it to the minimum of 1 ms fixes this.

Input: tsc200x - report proper input_dev name

2016-08-10T09:49:26+00:00

commit e9003c9cfaa17d26991688268b04244adb67ee2b upstream.

Passes input_id struct to the common probe function for the tsc200x drivers
instead of just the bustype.

This allows for the use of the product variable to set the input_dev->name
variable according to the type of touchscreen used. Note that when we
introduced support for TSC2004 we started calling everything TSC200X, so
let's keep this quirk.

Input: xpad - fix oops when attaching an unknown Xbox One gamepad

2016-08-10T09:49:26+00:00

commit c7f1429389ec1aa25e042bb13451385fbb596f8c upstream.

Xbox One controllers have multiple interfaces which all have the
same class, subclass, and protocol. One of the these interfaces
has only a single endpoint. When Xpad attempts to bind to this
interface, it causes an oops when trying initialize the output URB
by trying to access the second endpoint's descriptor.

This situation was avoided for known Xbox One devices by checking
the XTYPE constant associated with the VID and PID tuple. However,
this breaks when new or previously unknown Xbox One controllers
are attached to the system.

This change addresses the problem by deriving the XTYPE for Xbox
One controllers based on the interface protocol before checking
the interface number.

commit 226ba707744a51acb4244724e09caacb1d96aed9 upstream.

The touchpad in HP Pavilion 14-ab057ca reports it's version as 12 and
according to Elan both 11 and 12 are valid IC types and should be
identified as hw_version 4.

Input: vmmouse - remove port reservation

2016-08-10T09:49:26+00:00

commit 60842ef8128e7bf58c024814cd0dc14319232b6c upstream.

The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource.  This
causes the port to be reserved by the APCI module as the system comes up,
making it unavailable to be reserved again by other drivers, thus
preserving this VMWare port for special use in a VMWare guest.

This port is designed to be shared among multiple VMWare services, such as
the VMMOUSE.  Because of this, VMMOUSE should not try to reserve this port
on its own.

The VMWare non-EFI BIOS does not do this to preserve compatibility with
existing/legacy VMs.  It is known that there is small chance a VM may be
configured such that these ports get reserved by other non-VMWare devices,
and if this ever happens, the result is undefined.

Input: uinput - handle compat ioctl for UI_SET_PHYS

commit affa80bd97f7ca282d1faa91667b3ee9e4c590e6 upstream.

When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS
ioctl needs to be treated with special care, as it has the pointer
size encoded in the command.
