Subject: [PATCH 12/76] thermal: remove useless call to
|
|
|
|
|
thermal_zone_device_set_polling
|
|
|
|
|
|
|
|
|
|
When the thermal zone has no get_temp callback then thermal_zone_device_register()
|
|
|
|
|
calls thermal_zone_device_set_polling() with a polling delay of 0. This
|
|
|
|
|
only cancels the poll_queue. Since the poll_queue hasn't been scheduled this
|
|
|
|
|
is a no-op. Remove it.
