Subject: [PATCH] HID: hid-sensor-hub: Fix issue with devices with no report ID
Date: Mon, 2 Nov 2020 19:29:39 -0500 [thread overview]
Message-ID: <20201103002939.688690-1-pceballos@google.com> (raw)
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.
