USB: Support for BT On-Air USB modem in cdc-acm.c
The patch below is a necessary workaround to support the BT On-Air USB modem, which fails to initialise properly during normal probing thus: Sep 30 17:34:57 sled kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references Sep 30 17:34:57 sled kernel: cdc_acm: probe of 1-1.2:1.0 failed with error -22 Adding the patch below causes the probing section to be skipped, and the modem then initialises correctly.
