[PATCH AUTOSEL 5.9 06/33] HID: hid-sensor-hub: Fix issue with devices with no report ID

[Sasha Levin <sashal@kernel.org>]

From: Pablo Ceballos <pceballos@google.com>

[ Upstream commit 34a9fa2025d9d3177c99351c7aaf256c5f50691f ]

Some HID devices don't use a report ID because they only have a single
report. In those cases, the report ID in struct hid_report will be zero
and the data for the report will start at the first byte, so don't skip
over the first byte.
