[PATCH 6.6 076/331] iio: hid-sensor-als: Return 0 for HID_USAGE_SENSOR_TIME_TIMESTAMP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx>

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.
