Subject: [PATCH 19/42] thermal/drivers/mediatek: Change clk_prepare_enable to
|
||
|
|
devm_clk_get_enabled in mtk_thermal_probe
|
||
|
|
|
||
|
|
Use devm_clk_get_enabled to do automatic resource management.
|
||
|
|
Meanwhile, remove error handling labels in the probe function and
|
||
|
|
the whole remove function.
