Hello, I am new to kernel driver stuff. Basically, I would like to change the number of allowed devices for USB cdc_acm driver (it only allow 32, I want 128). I made the change, the compile passed, but the vermagic number doesn't match the original kernel's. I copied the config file form /boot/. Any one can tell me what do I have to do to make the vermagic the same. By the way, my kernel source is the same version as the original kernel.
