Subject: [PATCH AUTOSEL 4.19 04/15] HID: hid-sensor-hub: Fix issue with devices with no report ID
Date: Wed, 25 Nov 2020 10:37:01 -0500	[thread overview]
Message-ID: <20201125153712.810655-4-sashal@kernel.org> (raw)
In-Reply-To: <20201125153712.810655-1-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.
