Yes, I noticed this, and it looks like unnecessary change, and I just replied in
mail that I will change it back to arch_initcall() in order to make sure nothing
changed for built-in config. Below is what I replied in cover-letter mail:

" I will keep the arch_initcall() there in next version patch series, it can make sure
the change does NOT impact built-in config. For module build, the arch_initcall()
will be same as module_init(), user needs to insmod the .ko with correct sequence."

Thanks,
Anson
