Merge branch 'for-6.3/hid-bpf' into for-linus

2023-02-22T09:44:31+00:00

Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Conflicts:
* drivers/hid/i2c-hid/Kconfig:
  commit bf7660dab30d ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd165 ("HID: fix I2C_HID not selected
  when I2C_HID_OF_ELAN is")
  the resolution is simple enough: just drop the "default" and "select"
  lines as the new commit from Arnd is doing

Merge branch 'for-6.3/multitouch' into for-linus

Allow to pass quirks from i2c-hid to hid-multitouch (Allen Ballway &
Dmitry Torokhov)

HID: retain initial quirks set up when creating HID devices

2023-02-09T13:24:30+00:00

In certain circumstances, such as when creating I2C-connected HID
devices, we want to pass and retain some quirks (axis inversion, etc).
The source of such quirks may be device tree, or DMI data, or something
else not readily available to the HID core itself and therefore cannot
be reconstructed easily. To allow this, introduce "initial_quirks" field
in hid_device structure and use it when determining the final set of
quirks.

This fixes the problem with i2c-hid setting up device-tree sourced
quirks too late and losing them on device rebind, and also allows to
sever the tie between hid-code and i2c-hid when applying DMI-based
quirks.

Fixes: b60d3c803d76 ("HID: i2c-hid-of: Expose the touchscreen-inverted properties")
Fixes: a2f416bf062a ("HID: multitouch: Add quirks for flipped axes")

HID: use standard debug APIs

2023-02-06T14:11:45+00:00

The custom "debug" module parameter is fairly inflexible.
It can only manage debugging for all calls dbg_hid() at the same time.

Furthermore it creates a mismatch between calls to hid_dbg() which can
be managed by CONFIG_DYNAMIC_DEBUG and dbg_hid() which is managed by the
module parameter.

Furthermore the change to pr_debug() allows the debugging statements to
be completely compiled-out if desired.
