Input: tsc200x - report proper input_dev name

2016-08-10T10:54:45+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: synaptics-rmi4 - fix maximum size check for F12 control register 8

2016-08-10T10:54:45+00:00

commit e4add7b6beaff4061693d0632bc1dcb306edba10 upstream.

According to the RMI4 spec the maximum size of F12 control register 8 is
15 bytes. The current code incorrectly reports an error if control 8 is
greater then 14. Making sensors with a control register 8 with 15 bytes
unusable.

Revert "Input: wacom_w8001 - drop use of ABS_MT_TOOL_TYPE"

2016-08-10T10:54:45+00:00

commit 3e9161bfe0482f26efeaf584d5fd69398c69313c upstream.

This reverts commit 5f7e5445a2de848c66d2d80ba5479197e8287c33 because
removal of input_mt_report_slot_state() means we no longer generate
tracking IDs for the reported contacts.

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

2016-08-10T10:54:45+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.

Input: vmmouse - remove port reservation

2016-08-10T10:54:45+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: xpad - prevent spurious input from wired Xbox 360 controllers

2016-06-08T01:23:35+00:00

commit 1ff5fa3c6732f08e01ae12f12286d4728c9e4d86 upstream.

After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.

Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.

Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.

The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03
08 03 00
