Patch 17dd3f0f7a: "[PATCH] drivers/input/joystick: convert to dynamic
input_dev allocation" from Sep 15, 2005, leads to the following static
checker warning:
drivers/input/joystick/turbografx.c:235 tgfx_probe()
error: buffer overflow 'tgfx_buttons' 5 <= 5
drivers/input/joystick/turbografx.c
195 for (i = 0; i < n_devs; i++) {
196 if (n_buttons[i] < 1)
197 continue;
198
199 if (n_buttons[i] > 6) {
^^^^^^^^^^^^^^^^
Possibly off by one. >= 6.
Let's change the upper value to ARRAY_SIZE(tgfx_buttons) to ensure we do
not reach past the end of the array.

The controller only receives commands when its present. So for the
correct LED to be lit the LED command has to be sent on the present
event.

Based on Patch by Pierre-Loup A. Griffais <pgriffais@valvesoftware.com>:
Add the logic to set the LEDs on XBox Wireless controllers. Command
sequence found by sniffing the Windows data stream when plugging the
device in.
Updated based on comments on linux-input:
unify codepaths in xpad_send_led_command for wired/ wireless controller.
Also document command values for clarification.
All values tested on Xbox 360 Wireless Controller.

The input_free_device() function tests whether its argument is NULL and
then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.

The current codes in gameport and analog joystick drivers for the time
accounting have a long-standing problem when the system is running
with CPU freq; since the timing is measured via TSC or sample counter,
the calculation isn't reliable.
In this patch, as a simple fix, use the standard ktime to measure the
timing. In case where no high resolution timer is available,
use_ktime bool option is provided to both modules. Setting
use_ktime=false switches to the old methods.

The xpad driver recognizes Razer Sabertooth controllers as generic xbox

Xbox One controllers require an initialization message to start sending
data, so xpad_init_output becomes a required function. The Xbox One
controller does not have LEDs like the Xbox 360 controller, so that
functionality is not implemented. The format of messages controlling rumble
is currently undocumented, so rumble support is not yet implemented.
Note that Xbox One controller advertises three interfaces with the same
interface class, subclass and protocol, so we have to also match against
interface number.

As with ARM the ARMv8 architecture provides a cycle counter which can be
used to provide a high resolution time for the joystick driver and
silence the build warning that results from not having a precise timer
on ARMv8, making allmodconfig and allyesconfig quieter.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

When using Razer Onza controller the dpad doesn't work in many games
because D-PAD was mapped to buttons (useful for dance pads) and not to
HAT0X/Y axis.
ers who really want to have it mapped to buttons can restore previous
behavior by using 'dpad_to_buttons' module option.
