hwmon/drivers/core: Simplify complex dependency
As the thermal framework does not longer compile as a module, we can
simplify this condition below:
if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \
(!defined(CONFIG_THERMAL_HWMON) || \
!(defined(MODULE) && IS_MODULE(CONFIG_THERMAL)))
if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \
(!defined(CONFIG_THERMAL_HWMON) || \
!(defined(MODULE) && 0))
=> (whatever && 0) = 0
if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \
(!defined(CONFIG_THERMAL_HWMON) || !(0))
if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \
(!defined(CONFIG_THERMAL_HWMON) || 1)
=> (whatever || 1) = 1
if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF) && \
(1)
=> (whatever && 1) = whatever
if IS_REACHABLE(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF)
CONFIG_THERMAL can not be a module anymore, then:
if defined(CONFIG_THERMAL) && defined(CONFIG_THERMAL_OF)
And CONFIG_THERMAL_OF already depends on CONFIG_THERMAL, so:
if defined(CONFIG_THERMAL_OF)
Thus,
ifdef CONFIG_THERMAL_OF
