Build failure on branch updates-lcd_bus-drivers: missing ext_mod/lcd_bus/common_src/i2c_bus.c

[kapest007]

I tried to build lvgl_micropython on Raspberry Pi Pico 2.

Branch:
updates-lcd_bus-drivers

Command:
python3 make.py rp2 BOARD=RPI_PICO2 DISPLAY=ili9488 INDEV=xpt2046

The build stops with:

Cannot find source file:
ext_mod/lcd_bus/common_src/i2c_bus.c

The file is referenced in:
ext_mod/lcd_bus/micropython.cmake

but the directory common_src does not exist in this checkout.

Repository state:
commit:

It looks like the branch contains a reference to a file which is not included.
