of 0s copied into user buffer, if we directly copy to user buffer from report->field[]->value This change will copy report size bytes into the buffer of caller for each usage report->field[]->value. So for example without this change, the data displayed for a custom sensor field "sensor-model": 76 00 101 00 110 00 111 00 118 00 111 (truncated to report count of 11) With change 76 101 110 111 118 111 32 89 111 103 97 ("Lenovo Yoga" in ASCII ) Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
