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