Subject: [PATCH v2 0/2] HID: hid-goodix: Improve handling of HID feature reports

The patchset introduces the following two changes:

1) Align with the i2c-hid driver by returning 0 instead of -EINVAL when
an empty response is received, ensuring that userspace programs utilizing
the hidraw node receive consistent return values.

2) Implement the hid get/set feature report function using a separate
address, rather than sharing an address with coordinate reporting, to
prevent feature events from being overwritten by coordinate events.
