[PATCH 0/3] hwmon: (cros_ec) Synchronize EC access from the thermal device callbacks

Posted by Thomas Weißschuh 2 weeks ago

To guarantee consistency for the read-modify-write access in
cros_ec_hwmon_cooling_set_cur_state(), locking is necessary.

Use the existing hwmon device lock to do so.

Sung-Chi: Could you test this? I do not have access to hardware which
triggers this code path.
