Ismael Ferreras Morezuelas 9284d3b9a3 Input: xpad - spelling fixes for "Xbox"
The Linux kernel is notorious for misspelling X-Box, X-box, XBox or XBOX;
the official spelling is actually just Xbox. Plain and simple.

Tried to respect the existing notes but still following the style guide.
No functional changes intended. This only affects ancillary parts.

Niklas Schnelle 50cd8714a1 Input: add HAS_IOPORT dependencies
In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.

Dmitry Torokhov f219050af0 Input: libps2 - do not discard non-ack bytes when controlling LEDs
Upon receiving a PS/2 command the device and controller are supposed to
stop sending normal data (scancodes or movement packets) and instead
immediately start delivering ACK/NAK and command response. Unfortunately
often EC has an output buffer which may contain latched data by the time
the EC receives a command from the host. The kernel used to ignore such
data, but that may cause "stuck" keys if the data dropped happens to be a
break code or a part of a break code. This occasionally happens, for
example, on Chromebooks when the kernel tries to toggle CapsLock LED on
a keyboard while user releases Alt+Search keyboard shortcut.

Fix this by passing the first non-ACK byte to the normal handler for a
handful of PS/2 commands that are expected to be used during normal device
operation (as opposed to probe/configuration time).

Dmitry Torokhov c4c7eac8ee Input: libps2 - introduce common interrupt handler
Instead of exposing inner workings of libps2 to drivers such as atkbd and
psmouse, have them define pre-receive and receive callbacks, and provide a
common handler that can be used with underlying serio port.

While at this add kerneldoc to the module.

Dmitry Torokhov df9fe0e653 Input: libps2 - rework handling of command response
It is not entirely correct that libps2 sets PS2_FLAG_CMD1 after
the device acknowledges each byte sent to the device by the host.
Rework the code so that PS2_FLAG_CMD1 and PS2_FLAG_CMD are set only once,
at the beginning of PS/2 command execution.

Dmitry Torokhov fc522f3bdf Input: libps2 - remove special handling of ACK for command byte
When getting unexpected data while waiting for an acknowledgement it does
not matter what command phase is currently executed, and ps2_handle_ack()
should indicate that no further processing is needed for the received data
byte. Remove PS2_FLAG_ACK_CMD and associated handling.

Note that while it is possible to make ps2_handle_ack (and
ps2_handle_repsonse) return void, it will be done when the code will be
converted to common PS/2 interrupt handler later.

Maximilian Weigand 3c98b8dbdc Input: cyttsp5 - implement proper sleep and wakeup procedures
The touchscreen can be put into a deep sleep state that prevents it from
emitting touch irqs. Put the touchscreen into deep sleep during suspend
if it is not marked as a wakeup source.

This also fixes a problem with the touchscreen getting unresponsive after
system resume when a falling edge trigger is used for the interrupt.
When left on during suspend, the touchscreen would pull the interrupt
line down in response to touch events, leaving the interrupt effectively
disabled after resume.

As per the comments for input_allocate_device() and
input_register_device(), input_free_device() must be called only to free
devices that have not been registered.  input_unregister_device()
already calls input_put_device(), thus leading to a use-after-free.

Moreover, the kunit_suite.exit() method is called after every test case,
even on failures.  As the test itself already does cleanups in its
failure paths, this may lead to a second use-after-free.

Fix the first issue by dropping the call to input_allocate_device() from
input_test_exit().
Fix the second issue by making the cleanup code conditional on a
successful test.

Duoming Zhou dbe836576f Input: cyttsp4_core - change del_timer_sync() to timer_shutdown_sync()
The watchdog_timer can schedule tx_timeout_task and watchdog_work
can also arm watchdog_timer. The process is shown below:

----------- timer schedules work ------------
cyttsp4_watchdog_timer() //timer handler
  schedule_work(&cd->watchdog_work)

----------- work arms timer ------------
cyttsp4_watchdog_work() //workqueue callback function
  cyttsp4_start_wd_timer()
    mod_timer(&cd->watchdog_timer, ...)

Although del_timer_sync() and cancel_work_sync() are called in
cyttsp4_remove(), the timer and workqueue could still be rearmed.
As a result, the possible use after free bugs could happen. The
process is shown below:

  (cleanup routine)           |  (timer and workqueue routine)
cyttsp4_remove()              | cyttsp4_watchdog_timer() //timer
  cyttsp4_stop_wd_timer()     |   schedule_work()
    del_timer_sync()          |
                              | cyttsp4_watchdog_work() //worker
                              |   cyttsp4_start_wd_timer()
                              |     mod_timer()
    cancel_work_sync()        |
                              | cyttsp4_watchdog_timer() //timer
                              |   schedule_work()

                              |   cd-> //USE

This patch changes del_timer_sync() to timer_shutdown_sync(),

Luca Weiss d09dbc7a01 Input: drv260x - fix magnitude handling
First of all, previously the 16-bit magnitude was written as-is to the
device which actually discarded the upper 8 bits since the device has
8-bit registers only. This meant that a strong_magnitude of 0xFF00 would
result in 0. To correct this shift the strong_magnitude / weak_magnitude
input values so we discard the lower 8 bits and keep the upper bits
instead.

Secondly the RTP mode that is used by default interprets the values as
signed (2s complement), so 0x81 = 0%, 0x00 = 50%, 0x7F = 100%. This
doesn't match the FF_RUMBLE interface at all, so let's tell the device
to interpret the data as unsigned instead which gets us 0x00 = 0% and
0xFF = 100%.

As last change switch ERM to using "Closed-Loop Mode, Unidirectional"
instead of "Open-Loop Mode" since it's recommended by the datasheet
compared to open loop and better matches our use case of 0% - 100%
vibration.

It is pointless and expensive to calculate data in the interrupt that

probe and cannot then be changed.
