<title>Input: xpad - delete a Razer DeathAdder mouse VID/PID entry</title>

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]: https://github.com/libsdl-org/SDL/blob/dcc5eef0e2395854b254ea2873a4899edab347c6/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 },

Actual change in SDL2 referencing this kernel issue:
https://github.com/libsdl-org/SDL/commit/e5e54169754ca5d3e86339d968b20126d9da0a15

For more information of the device, take a look here:
https://github.com/xboxdrv/xboxdrv/pull/59

You can see a lsusb dump here: https://github.com/xboxdrv/xboxdrv/files/76581/Qa6dBcrv.txt

commit b8ebf250997c5fb253582f42bfe98673801ebebd upstream.

syzbot is reporting uninitialized value at iforce_init_device() [1], for
commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer
when fetching device IDs") is checking that valid length is shorter than
bytes to read. Since iforce_get_id_packet() stores valid length when
returning 0, the caller needs to check that valid length is longer than or
equals to bytes to read.

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.

commit 98e01215708b6d416345465c09dce2bd4868c67a upstream.

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

It seems that the cause is simply that commit c2b27ef672992a20 ("Input:
iforce - wait for command completion when closing the device") forgot to
call wake_up() after clear_bit().

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