2015-01-12usb: serial: handle -ENODEV quietly in generic_submit_read_urbJeremiah Mahler
If a USB serial device (e.g. /dev/ttyUSB0) with an active program is unplugged, an -ENODEV (19) error will be produced after it gives up trying to resubmit a read. usb_serial_generic_submit_read_urb - usb_submit_urb failed: -19 Add -ENODEV as one of the permanent errors along with -EPERM that usb_serial_generic_submit_read_urb() handles quietly without an error.

2015-01-12usb: serial: silence all non-critical read errorsJeremiah Mahler
If a USB serial device is unplugged while there is an active program using the device it may spam the logs with -EPROTO (71) messages as it attempts to retry. Most serial usb drivers (metro-usb, pl2303, mos7840, ...) only output these messages for debugging. The generic driver treats these as errors. Change the default output for the generic serial driver from error to debug to silence these non-critical errors.

2015-01-10USB: console: fix potential use after freeJohan Hovold
Use tty kref to release the fake tty in usb_console_setup to avoid use after free if the underlying serial driver has acquired a reference. Note that using the tty destructor release_one_tty requires some more state to be initialised.

2015-01-10USB: console: fix uninitialised ldisc semaphoreJohan Hovold
The USB console currently allocates a temporary fake tty which is used to pass terminal settings to the underlying serial driver. The tty struct is not fully initialised, something which can lead to a lockdep warning (or worse) if a serial driver tries to acquire a line-discipline reference: usbserial: USB Serial support registered for pl2303 pl2303 1-2.1:1.0: pl2303 converter detected usb 1-2.1: pl2303 converter now attached to ttyUSB0 INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

2014-09-15USB: serial: remove zte_ev driverJohan Hovold
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 Mork
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.
