Revert "USB: option,zte_ev: move most ZTE CDMA devices to zte_ev"

2014-08-18T11:09:25+00:00

This reverts commit 73228a0538a7 ("USB: option,zte_ev: move most ZTE
CDMA devices to zte_ev").

Move the IDs of the devices that were previously driven by the option
driver back to that driver.

As several users have reported, the zte_ev driver is causing random
disconnects as well as reconnect failures.

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 Liu Lei, it fails to lower DTR/RTS on close. It also appears
that the control requests lack the interface argument.

Note that 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.

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), this is a first step in ultimately removing the redundant
zte_ev driver.

Note that AC2726 had already been moved back to option, and that some
IDs were in the device table of both drivers prior to the commit being
reverted.

USB: option: reduce interrupt-urb logging verbosity

2014-08-18T09:05:37+00:00

Do not log normal interrupt-urb shutdowns as errors.

The option driver has always been logging any nonzero interrupt-urb
status as an error, including when the urb is killed during normal
operation.

Commit 9096f1fbba91 ("USB: usb_wwan: fix potential NULL-deref at
resume") moved the interrupt urb submission from port probe and release
to open and close, thus potentially increasing the number of these
false-positive error messages dramatically.

USB: option: add device ID for SpeedUp SU9800 usb 3g modem

2014-06-23T10:24:53+00:00

Reported by Alif Mubarak Ahmad:

This device vendor and product id is 1c9e:9800
It is working as serial interface with generic usbserial driver.
I thought it is more suitable to use usbserial option driver, which has
better capability distinguishing between modem serial interface and
micro sd storage interface.

USB: usb_wwan: remove unimplemented set_termios

2014-05-27T22:04:07+00:00

The driver does not implement set_termios so the operation can be left
unset (tty will do the tty_termios_copy_hw for us).

Note that the send_setup call is bogus as it really only sets DTR/RTS
to their current values.
