I get following with your config:

LD      init/built-in.o
drivers/built-in.o: In function `v4l2_device_unregister':
(.text+0x1186cb): undefined reference to `i2c_unregister_device'
make: *** [vmlinux] Error 1

and it looks like it wants to build in videodev.o (which provides
v4l2_device_unregister()):

CONFIG_VIDEO_DEV=y

This function calls i2c_unregister_device() if IS_ENABLED(CONFIG_I2C) but
i2c support is compiled as a module:

CONFIG_I2C=m

which explains the link error.

However, this has nothing to do with clk-lpt.c or anything related to clock
framework as far as I can tell.
