Subject: [PATCH] HID: hid-sensor-hub: fix report size
Date: Fri, 18 Oct 2013 09:48:44 -0700	[thread overview]
Message-ID: <1382114924-25654-1-git-send-email-srinivas.pandruvada@linux.intel.com> (raw)

The number of bytes in a field needs to take account of report_count
field. Need to multiply report_size and report_count to get total
number of bytes.
