Hi,

config EXTCON_PTN5150
	tristate "NXP PTN5150 CC LOGIC USB EXTCON support"
	depends on I2C && GPIOLIB || COMPILE_TEST
	select REGMAP_I2C

Where did the " || COMPILE_TEST" come from?

I generally support using COMPILE_TEST, but in this case it causes
problems, when EXTCON_PTN5150=y and I2C=m (and COMPILE_TEST=y),
both in kconfig and in build errors:
