282a96e3f8 Input: xpad - delete a Razer DeathAdder mouse VID/PID entry
commit feee70f4568650cf44c573488798ffc0a2faeea3 upstream.

While doing my research to improve the xpad device names I noticed
that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013,
so that Razer Sabertooth instance looked wrong and very suspect to
me. I didn't see any mention in the official drivers, either.

After doing more research, it turns out that the xpad list
is used by many other projects (like Steam) as-is [1], this
issue was reported [2] and Valve/Sam Lantinga fixed it [3]:

[1]: dcc5eef0e2/src/joystick/controller_type.h (L251)
[2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/
[3]: https://hg.libsdl.org/SDL/rev/29809f6f0271

(With multiple Internet users reporting similar issues, not linked here)

After not being able to find the correct VID/PID combination anywhere
on the Internet and not receiving any reply from Razer support I did
some additional detective work, it seems like it presents itself as
"Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00.

Leaving us with this:
 * Razer Sabertooth (1689:fe00)
 * Razer Sabertooth Elite (24c6:5d04)
 * Razer DeathAdder 2013 (1532:0037) [note: not a gamepad]

So, to sum things up; remove this conflicting/duplicate entry:

{ 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 },

As the real/correct one is already present there, even if
the Internet as a whole insists on presenting it as the
Razer Sabertooth Elite, which (by all accounts) is not:

{ 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 },

commit a17b9841152e7f4621619902b347e2cc39c32996 upstream.

Suspending and resuming the system can sometimes cause the out
URB to get hung after a reset_resume. This causes LED setting
and force feedback to break on resume. To avoid this, just drop
the reset_resume callback so the USB core rebinds xpad to the
wireless pads on resume if a reset happened.

A nice side effect of this change is the LED ring on wireless
controllers is now set correctly on system resume.

syzbot is reporting hung task at __input_unregister_device() [1], for
iforce_close() waiting at wait_event_interruptible() with dev->mutex held
is blocking input_disconnect_device() from __input_unregister_device().

It seems that the cause is simply that commit c2b27ef672 ("Input:

call wake_up() after clear_bit().

Fix this problem by introducing a helper that calls clear_bit() followed
by wake_up_all().

46556c4ecd Input: spaceball - fix parsing of movement data packets
commit bc7ec91718c49d938849697cfad98fcd9877cc26 upstream.

The spaceball.c module was not properly parsing the movement reports
coming from the device.  The code read axis data as signed 16-bit
little-endian values starting at offset 2.

In fact, axis data in Spaceball movement reports are signed 16-bit
big-endian values starting at offset 3.  This was determined first by
visually inspecting the data packets, and later verified by consulting:
http://spacemice.org/pdf/SpaceBall_2003-3003_Protocol.pdf

If this ever worked properly, it was in the time before Git...

2178db65cd Input: iforce - drop bus type from iforce structure
It is not needed anymore as behavior is controlled by the transport
operations set up for given device.

dfad2b1793 Input: iforce - use DMA-safe buffores for USB transfers
USB transport has to use cache line-aligned buffers for transfers to avoid
DMA issues; serio doe snot have such restrictions. Let's move "data_in"
buffer from main driver structure into transport modules and make sure USB
requirements are respected.

6ac0aec6b0 Input: iforce - allow callers supply data buffer when fetching device IDs
We want to move buffer handling into transport layers as the properties of
buffers (DMA-safety, alignment, etc) are different for different
transports. To allow this, let's allow caller to specify their own buffers
for the results of iforce_get_id_packet() and let transport drivers to
figure what buffers they need to use for transfers.

633354d191 Input: iforce - only call iforce_process_packet() if initialized
It is excessive to check if device is fully initialized in
iforce_process_packet(), as for USB-conected devices we do not start
collecting reports until the device is fully initialized.

Let's change serio transport code to not call iforce_process_packet()
until device initialization is done.

2880dcf9cf Input: iforce - signal command completion from transport code
Signalling command completion from iforce_process_packet() does
not make sense, as not all transport use the same data path for
both commands and motion data form the device, that is why USB
code already has to signal command completion iforce_usb_out().

Let's move signalling completion into individual transport
modules.

d3cc100069 Input: iforce - do not combine arguments for iforce_process_packet()
Current code combines packet type and data length into single argument to
iforce_process_packet() and then has to untangle it. It is much clearer to
simply use separate arguments.

4873586278 Input: iforce - use DMA-safe buffer when getting IDs from USB
When working with USB devices we need to use DMA-safe buffers,
and iforce->edata is not one. Let's rework the code to allocate
temporary buffer (iforce_get_id() is called only during initialization
so there is no reason to have permanent buffer) and use it. While at it,
let's utilize usb_control_msg() API which simplifies code.
