USB: serial: add qualcomm wireless modem driver Driver originally written by Qualcomm, but rewritten by me due to the totally different coding style. Cleaned up the probe logic to make a bit more sense, this is one wierd device. They could have prevented all of this by just writing sane firmware for the modem.
