1 year ago I got a similar error as this. I simply changed the two lines where ch34x_write_room is called from int to unsigned int (lines 942 and 946 for me respectively). This fixed the error. Same thing for the ch34x_chars_in_buffer (lines 968 and 972 for me respectively).
Your lines may be slightly different but the solution should be the same. Hope this helps!
When running the make command, I came across the following errors:
