USB: zte_ev: fix removed PIDs

2014-10-05T20:40:58+00:00

commit 3096691011d01cef56b243a5e65431405c07d574 upstream.

Add back some PIDs that were mistakingly remove when reverting commit
73228a0538a7 ("USB: option,zte_ev: move most ZTE CDMA devices to
zte_ev"), which apparently did more than its commit message claimed in
that it not only moved some PIDs from option to zte_ev but also added
some new ones.

USB: sierra: avoid CDC class functions on "68A3" devices

2014-10-05T20:40:57+00:00

commit 049255f51644c1105775af228396d187402a5934 upstream.

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.

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

2014-10-05T20:40:57+00:00

commit 63a901c06e3c2c45bd601916fe04e870e9ccae1e upstream.

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

2014-10-05T20:40:57+00:00

commit f0e4cba2534cd88476dff920727c81350130f3c5 upstream.

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.
