1353ecaf18 HID: amd_sfh: Add support for shutdown operation
As soon as the system is booted after shutdown, the sensors may remain in
a weird state and fail to initialize. Therefore, all sensors should be
turned off during shutdown.

38518593ec HID: intel-ish-hid: Fix kernel panic during warm reset
During warm reset device->fw_client is set to NULL. If a bus driver is
registered after this NULL setting and before new firmware clients are
enumerated by ISHTP, kernel panic will result in the function
ishtp_cl_bus_match(). This is because of reference to
device->fw_client->props.protocol_name.

ISH firmware after getting successfully loaded, sends a warm reset
notification to remove all clients from the bus and sets
device->fw_client to NULL. Until kernel v5.15, all enabled ISHTP kernel
module drivers were loaded right after any of the first ISHTP device was
registered, regardless of whether it was a matched or an unmatched
device. This resulted in all drivers getting registered much before the
warm reset notification from ISH.

Starting kernel v5.16, this issue got exposed after the change was
introduced to load only bus drivers for the respective matching devices.
In this scenario, cros_ec_ishtp device and cros_ec_ishtp driver are
registered after the warm reset device fw_client NULL setting.
cros_ec_ishtp driver_register() triggers the callback to
ishtp_cl_bus_match() to match ISHTP driver to the device and causes kernel
panic in guid_equal() when dereferencing fw_client NULL pointer to get
protocol_name.

7c3650a800 HID: hid-sensor-custom: Fix buffer overrun in device name
On some platforms there are some platform devices created with
invalid names. For example: "HID-SENSOR-INT-020b?.39.auto" instead
of "HID-SENSOR-INT-020b.39.auto"

This string include some invalid characters, hence it will fail to
properly load the driver which will handle this custom sensor. Also
it is a problem for some user space tools, which parses the device
names from ftrace and dmesg.

This is because the string, real_usage, is not NULL terminated and
printed with %s to form device name.

To address this, initialize the real_usage string with 0s.

17d793f3ed HID: wacom: insert timestamp to packed Bluetooth (BT) events
To fully utilize the BT polling/refresh rate, a few input events
are sent together to reduce event delay. This causes issue to the
timestamp generated by input_sync since all the events in the same
packet would pretty much have the same timestamp. This patch inserts
time interval to the events by averaging the total time used for
sending the packet.

This decision was mainly based on observing the actual time interval
between each BT polling. The interval doesn't seem to be constant,
due to the network and system environment. So, using solutions other
than averaging doesn't end up with valid timestamps.

a93e884edf Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
 
 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

37f5b858a6 HID: cp2112: Fix driver not registering GPIO IRQ chip as threaded
The CP2112 generates interrupts from a polling routine on a thread,
and can only support threaded interrupts. This patch configures the
gpiochip irq chip with this flag, disallowing consumers to request
a hard IRQ from this driver, which resulted in a segfault previously.

1c5d422124 HID: uhid: Over-ride the default maximum data buffer value with our own
The default maximum data buffer size for this interface is UHID_DATA_MAX
(4k).  When data buffers are being processed, ensure this value is used
when ensuring the sanity, rather than a value between the user provided
value and HID_MAX_BUFFER_SIZE (16k).

b1a37ed00d HID: core: Provide new max_buffer_size attribute to over-ride the default
Presently, when a report is processed, its proposed size, provided by
the user of the API (as Report Size * Report Count) is compared against
the subsystem default HID_MAX_BUFFER_SIZE (16k).  However, some
low-level HID drivers allocate a reduced amount of memory to their
buffers (e.g. UHID only allocates UHID_DATA_MAX (4k) buffers), rending
this check inadequate in some cases.

In these circumstances, if the received report ends up being smaller
than the proposed report size, the remainder of the buffer is zeroed.
That is, the space between sizeof(csize) (size of the current report)
and the rsize (size proposed i.e. Report Size * Report Count), which can
be handled up to HID_MAX_BUFFER_SIZE (16k).  Meaning that memset()
shoots straight past the end of the buffer boundary and starts zeroing
out in-use values, often resulting in calamity.

This patch introduces a new variable into 'struct hid_ll_driver' where
individual low-level drivers can over-ride the default maximum value of
HID_MAX_BUFFER_SIZE (16k) with something more sympathetic to the
interface.

Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be

to v6.3.

  commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected
