USB: add Zoom Telephonics Model 3095F V.92 USB Mini External modem to cdc-acm
commit 6149ed5e3a6207595bd7362af7724d64f44af216 upstream
The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:
May 3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May 3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22
Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.
