Subject: [PATCH 03/42] thermal/drivers/mtk: Use function pointer for
|
|
raw_to_mcelsius
|
|
|
|
Instead of having if-else logic selecting either raw_to_mcelsius_v1 or
|
|
raw_to_mcelsius_v2 in mtk_thermal_bank_temperature introduce a function
|
|
pointer raw_to_mcelsius to struct mtk_thermal which is initialized in the
|
|
probe function.
