[PATCH 0/1] Fix I2C HID device failure when initialize touchpad

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/2061040

[Impact]
Sensel haptic pad doesn't work on boot.
Error log:
i2c_hid_acpi i2c-SNSL0028:00: device did not ack reset within 1000 ms
hid-generic 0018:2C2F:0028.0001: unknown main item tag 0x0

[Fix]
This issue is a regression of commit from v6.8-rc1 :
commit: af93a167eda9 ("HID: i2c-hid: Move i2c_hid_finish_hwreset() to after reading the report-descriptor")
Fix commit: ea36bf1827462 ("HID: i2c-hid: Revert to await reset ACK before reading report descriptor")

[Test]
Tested on hardware, touchpad works after boot.

[Where problems could occur]
It may break HID input.

It is a regression on 6.8-rc1, SRU for Noble only.
