Only warn once of oversize hid report value field
On HP spectre x360 convertible the message:
hid-sensor-hub 001F:8087:0AC2.0002: hid_field_extract() called with n (192) > 32! (kworker/1:2)
is continually printed many times per second, crowding out all else.
Protect dmesg by printing the warning only one time.
The size of the hid report field data structure should probably be increased.
The data structure is treated as a u32 in Linux, but an unlimited number
of bits in the USB hid spec, so there is some rearchitecture needed now that
devices are sending more than 32 bits.

- fnmode=2: hold F5, hold FN, release F5, release FN

Before this commit dj_probe would exit with an error if the initial
logi_dj_recv_query_paired_devices fails. The initial call may fail
when the receiver is connected through a kvm and the focus is away.
When the call fails this causes 2 problems:
1) dj_probe calls logi_dj_recv_query_paired_devices after calling
hid_device_io_start() so a HID report may have been received in between
and our delayedwork_callback may be running. It seems that the initial
logi_dj_recv_query_paired_devices failure happening with some KVMs triggers
this exact scenario, causing the work-queue to run on free-ed memory,
leading to:

2) Even if we were to fix 1. by making sure the work is stopped before
failing probe, failing probe is the wrong thing to do, we have
logi_dj_recv_queue_unknown_work to deal with the initial
logi_dj_recv_query_paired_devices failure.
Rather then error-ing out of the probe, causing the receiver to not work at
all we should rely on this, so that the attached devices will get properly
enumerated once the KVM focus is switched back.

It was a good idea at the time to not create a mouse node for the
multitouch touchscreens, but:
- touchscreens following the Win 8 protocol should not have this
disturbing mouse node anymore, or if they have, it should be
used for something else (like a joystick attached to the screen)
- touchpads have it, and they should not use it unless there is a bug,
but when the laptop has a trackstick, the data are reported through this
mouse node.
So instead of whitelisting all of the devices that have a need for the
mouse node, just export it.
hid-input.c will append a suffix to it ('Mouse'), so users will eventually
see if something goes wrong.

Currently, the NO_D3 flag is set in ish_probe(), and cleared in
ish_remove(). So even if the system goes into S3, ISH is still
in D0i3 state. It makes more sense that put ISH into D3 as system
goes into S3 and put ISH into D0i3 as system goes into suspend-to-idle.
I remove the NO_D3 setting in ish_probe(), so that ISH can enter
D3 state when system enters S3. Only set N0_D3 flag when system
enters the suspend-to-idle or platform specified, and clear it
when system resume.
When the ISH enters D3, the FW will check the DMA bit status.
If the DMA bit is set, the FW will reset automatically. So the
DMA bit need be clear before putting ISH into D3 state.

Valve reported a kernel crash on Ubuntu 18.04 when disconnecting a DS4
gamepad while rumble is enabled. This issue is reproducible with a
frequency of 1 in 3 times in the game Borderlands 2 when using an
automatic weapon, which triggers many rumble operations.
We found the issue to be a race condition between sony_remove and the
final device destruction by the HID / input system. The problem was
that sony_remove didn't clean some of its work_item state in
"struct sony_sc". After sony_remove work, the corresponding evdev
node was around for sufficient time for applications to still queue
rumble work after "sony_remove".
On pre-4.19 kernels the race condition caused a kernel crash due to a
NULL-pointer dereference as "sc->output_report_dmabuf" got freed during
sony_remove. On newer kernels this crash doesn't happen due the buffer
now being allocated using devm_kzalloc. However we can still queue work,
while the driver is an undefined state.
This patch fixes the described problem, by guarding the work_item
"state_worker" with an initialized variable, which we are setting back
to 0 on cleanup.

c01908a14b ("HID: input: add mapping for "Toggle Display" key") this
usage was being mapped to 'Relative.Misc'. After the patch it's simply
ignored (usage->type == 0 & usage->code == 0). Which ultimately makes
hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no
usage->type.
We shouldn't rely on a mapping for that usage as it's nonstandard and
doesn't really map to an input event. So we bypass the mapping and make
sure the custom event handling properly handles both reports.

Commit dbcbabf7da ("HID: logitech-dj: fix return value of

return the return value of hid_hw_raw_request instead of unconditionally
returning 0.
But hid_hw_raw_request returns the report-size on a successful request
(and a negative error-code on failure) where as the callers of
logi_dj_recv_query_hidpp_devices expect a 0 return on success.
This commit fixes things so that either the negative error gets returned
or 0 on success, fixing HID++ receivers such as the Logitech nano receivers
no longer working.

won't just be an obscure name.

- the first one converts stream_open.cocci to treat all functions that
start with wait_.* as blocking. Previously it was only wait_event_.*
functions that were considered as blocking, but this was falsely
reporting several deadlock cases as only warning. The patch was
picked by linux-kbuild and entered mainline as 0c4ab18fc3.
It is thus omitted from hereby pull-request.
- the second one teaches stream_open.cocci to consider files as being
stream-like even if they use noop_llseek. I posted this patch for
review 3 weeks ago[1], but got neither feedback nor complaints.

Merge tag 'stream_open-5.3' of https://lab.nexedi.com/kirr/linux
Pull stream_open() updates from Kirill Smelkov:
"This time on stream_open front it is only two small changes:
- the first one converts stream_open.cocci to treat all functions
that start with wait_.* as blocking. Previously it was only
wait_event_.* functions that were considered as blocking, but this
was falsely reporting several deadlock cases as only warning.
This was picked by linux-kbuild and entered mainline as commit
0c4ab18fc3 ("coccinelle: api/stream_open: treat all wait_.*()
calls as blocking"), and already merged earlier.
- the second one teaches stream_open.cocci to consider files as being
stream-like even if they use noop_llseek. It results in two more
drivers being converted to stream_open() (mousedev.c and
hid-sensor-custom.c)"
* tag 'stream_open-5.3' of https://lab.nexedi.com/kirr/linux:
*: convert stream-like files -> stream_open, even if they use noop_llseek
