From: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

commit 621c6257128149e45b36ffb973a01c3f3461b893 upstream.

When als_capture_sample() is called with usage ID
HID_USAGE_SENSOR_TIME_TIMESTAMP, return 0. The HID sensor core ignores
the return value for capture_sample() callback, so return value doesn't
make difference. But correct the return value to return success instead
of -EINVAL.
