2014-09-15USB: serial: remove zte_ev driverJohan Hovold4-315/+10
The zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Lei Liu, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1) let's remove the redundant zte_ev driver. Also move the remaining ZTE PIDs to the generic option modem driver. Reported-by: Lei Liu <liu.lei78@zte.com.cn> Signed-off-by: Johan Hovold <johan@kernel.org>

2014-09-01USB: sierra: avoid CDC class functions on "68A3" devicesBjørn Mork1-2/+4
Sierra Wireless Direct IP devices using the 68A3 product ID can be configured for modes including a CDC ECM class function. The known example uses interface numbers 12 and 13 for the ECM control and data interfaces respectively, consistent with CDC MBIM function interface numbering on other Sierra devices. It seems cleaner to restrict this driver to the ff/ff/ff vendor specific interfaces rather than increasing the already long interface number blacklist. This should be more future proof if Sierra adds more class functions using interface numbers not yet in the blacklist.
