In order to avoid opening a disconnected device, we need to check exist
again after acquiring the existance lock, and bail out if necessary.

1c703b53e5 HID: input: fix a4tech horizontal wheel custom usage
Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether
the previous wheel report was horizontal or vertical. Before
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.

7bc74853fd HID: quirks: Set the INCREMENT_USAGE_ON_DUPLICATE quirk on Saitek X52
The Saitek X52 joystick has a pair of axes that are originally
(by the Windows driver) used as mouse pointer controls. The corresponding
usage->hid values are 0x50024 and 0x50026. Thus they are handled
as unknown axes and both get mapped to ABS_MISC. The quirk makes
the second axis to be mapped to ABS_MISC1 and thus made available
separately.

6fb08f1a5f HID: logitech-dj: Really fix return value of logi_dj_recv_query_hidpp_devices
Commit dbcbabf7da ("HID: logitech-dj: fix return value of
logi_dj_recv_query_hidpp_devices") made logi_dj_recv_query_hidpp_devices
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.

Merge tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
  is mostly incremental work this time.

  Three important things:

   - The FMC subsystem is deleted through my tree. This happens through
     GPIO as its demise was discussed in relation to a patch decoupling
     its GPIO implementation from the standard way of handling GPIO. As
     it turns out, that is not the only subsystem it reimplements and
     the authors think it is better do scratch it and start over using
     the proper kernel subsystems than try to polish the rust shiny. See
     the commit (ACKed by the maintainers) for details.

   - Arnd made a small devres patch that was ACKed by Greg and goes into
     the device core.

   - SPDX header change colissions may happen, because at times I've
     seen that quite a lot changed during the -rc:s in regards to SPDX.
     (It is good stuff, tglx has me convinced, and it is worth the
     occasional pain.)

  Apart from this is is nothing controversial or problematic.

  Summary:

  Core:

   - When a gpio_chip request GPIOs from itself, it can now fully
     control the line characteristics, both machine and consumer flags.
     This makes a lot of sense, but took some time before I figured out
     that this is how it has to work.

   - Several smallish documentation fixes.

  New drivers:

   - The PCA953x driver now supports the TI TCA9539.

   - The DaVinci driver now supports the K3 AM654 SoCs.

0adcdbcb17 video: fbdev: don't print error message on framebuffer_alloc() failure
framebuffer_alloc() can fail only on kzalloc() memory allocation
failure and since kzalloc() will print error message in such case
we can omit printing extra error message in drivers (which BTW is
what the majority of framebuffer_alloc() users is doing already).

b12bbdc5dd HID: intel-ish-hid: fix wrong driver_data usage
Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.

So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function
that returns "struct ishtp_cl_device" from "struct device".

3a9a2c86ce HID: logitech-dj: Fix forwarding of very long HID++ reports
The HID++ spec also defines very long HID++ reports, with a reportid of
0x12. The MX5000 and MX5500 keyboards use 0x12 output reports for sending
messages to display on their buildin LCD.

Userspace (libmx5000) supports this, in order for this to work when talking
to the HID devices instantiated for the keyboard by hid-logitech-dj,
we need to properly forward these reports to the device.

This commit fixes logi_dj_ll_raw_request not forwarding these reports.

Finger data is separated into chunks in our Bluetooth report,
where each report contains the same number of chunks. Those chunks
are not aligned in any particular way to a set of finger touches.
That is, the first half of a group of simultaneous touches may
be in one chunk at the end of a report and the second half could
be at the beginning of the next report.

Also some chunks contain no data and potentially some chunks could
contain leftover (bad) data.

Introduce and process the WACOM_HID_WT_REPORT_VALID usage that the
device uses to let us know if we should process a chunk of data.

In the generic code path, HID_DG_CONTACTMAX was previously

Another report (0x82) has the HID_DG_CONTACTMAX in the
higher nibble of the third byte. We should support reading the
value of HID_DG_CONTACTMAX no matter what report we are reading
or which position that value is in.

To do this we submit the feature report as a event report
using hid_report_raw_event(). Our modified finger event path
records the value of HID_DG_CONTACTMAX when it sees that usage.

When a gpio_chip wants to request a descriptor from itself
using gpiochip_request_own_desc() it needs to be able to specify
fully how to use the descriptor, notably line inversion
semantics. The workaround in the gpiolib.c can be removed
and cases (such as SPI CS) where we need at times to request
a GPIO with line inversion semantics directly on a chip for
workarounds, can be fully supported with this call.

Fix up some users of the API that weren't really using the
last flag to set up the line as input or output properly
but instead just calling direction setting explicitly
after requesting the line.

3ed224e273 HID: logitech-dj: Fix 064d:c52f receiver support
The c52f nano receiver is a mouse only receiver. This means that it needs
some special handling compared to the c534 nano receiver:

1) It sends unnumbered mouse reports with a size of 8 bytes, so we need
   to extend the unnumbered mouse report handling to support reports upto
   8 bytes large

2) It mouse reports have the same high-resolution format as those from the
   gaming mouse receivers

3) It can report consumer/multimedia buttons on its second interface, since
   this is a mouse-only receiver these must be forwarded to the mouse child
   device and not to the keyboard child-device (which will not exist)
