No, this is not a left-over from the previous 2-module implementation of 
the cxl driver.
The file base.c is not part of the "normal" cxl driver. It is either 
part of the kernel if the cxl driver is a module or configured in the 
kernel. Or it is discarded if cxl is not even a module. So code in that 
file is either in the kernel or it's not even compiled. That was already 
the case on bare-metal.
Code in module_init() is executed when the kernel boots and it is not 
going away.
