Goodix Fingerprint device is not a modem

stable inclusion
from stable-5.10.24
commit b0db0c76a2ba8f3753120d5880ca58e69dba8f4d
bugzilla: 51348

--------------------------------

commit 4d8654e8 upstream.

The CDC ACM driver is false matching the Goodix Fingerprint device
against the USB_CDC_ACM_PROTO_AT_V25TER.

The Goodix Fingerprint device is a biometrics sensor that should be
handled in user-space. libfprint has some support for Goodix
fingerprint sensors, although not for this particular one. It is
possible that the vendor allocates a PID per OEM (Lenovo, Dell etc).
If this happens to be the case then more devices from the same vendor
could potentially match the ACM modem module table.
