[PATCH 5.15 55/82] iio: hid-sensors: Fix an error handling path in _hid_sensor_set_report_latency()

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

 



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

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

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

commit 3a29b84cf7fbf912a6ab1b9c886746f02b74ea25 upstream.

If hid_sensor_set_report_latency() fails, the error code should be returned
instead of a value likely to be interpreted as 'success'.
