-Subject: 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.
