2015-03-18USB: serial: fix tty-device error handling at probeJohan Hovold
commit ca4383a3947a83286bc9b9c598a1f55e867871d7 upstream. Add missing error handling when registering the tty device at port probe. This avoids trying to remove an uninitialised character device when the port device is removed.

2015-03-18USB: serial: fix potential use-after-free after failed probeJohan Hovold
commit 07fdfc5e9f1c966be8722e8fa927e5ea140df5ce upstream. Fix return value in probe error path, which could end up returning success (0) on errors. This could in turn lead to use-after-free or double free (e.g. in port_remove) when the port device is removed.

commit f528bf4f57e43d1af4b2a5c97f09e43e0338c105 upstream. Make sure to handle an infinite timeout (0). Note that wait_until_sent is currently never called with a 0-timeout argument due to a bug in tty_wait_until_sent.

2015-03-18usb: ftdi_sio: Add jtag quirk support for Cyber Cortex AV boardsMax Mansfield
commit c7d373c3f0da2b2b78c4b1ce5ae41485b3ef848c upstream. This patch integrates Cyber Cortex AV boards with the existing ftdi_jtag_quirk in order to use serial port 0 with JTAG which is required by the manufacturers' software. Steps: 2 [ftdi_sio_ids.h] 1. Defined the device PID [ftdi_sio.c] 2. Added a macro declaration to the ids array, in order to enable the jtag quirk for the device.

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.

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>
