[BUG] Compilation error with defined CASE_LIGHT_NO_BRIGHTNESS

[ABATAPA]

When CASE_LIGHT_NO_BRIGHTNESS is defined in Configuration_adv.h, compilation is aborted with an error:

sketch/src/lcd/extui/lib/dwin/DwinTFTCommand.cpp: In member function 'void DwinTFTCommandClass::handleSetCaseLight()':

I am trying to compile the firmware without PWM highlighting, because it flickers when printing (soft PWM?).

Arduino IDE 1.8.13 / master 3b083dd8a update to marlin 2.0.5.4
