The CDC-ACM part will be driven by cdc-acm, and the QCDM part gets driven by option.ko in parallel with the CDC-ACM. With these patches applied, you have both /dev/ttyACM0 (AT capable) and /dev/ttyUSB0 (QCDM capable). Somewhat like how the Ericsson "mbm" modems are concurrently driven by the cdc-wdm, cdc-ether, and cdc-acm class drivers all at the same time.
