Subject: [PATCH 4.9 13/42] HID: hid-sensor-hub: Fix issue with devices with no report ID
Date: Tue,  1 Dec 2020 09:53:11 +0100	[thread overview]
Message-ID: <20201201084642.846849568@linuxfoundation.org> (raw)
In-Reply-To: <20201201084642.194933793@linuxfoundation.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.
