USB: ftdi_sio: Add extra PID.

2014-08-06T17:07:37+00:00

commit 5a7fbe7e9ea0b1b9d7ffdba64db1faa3a259164c upstream.

This patch adds PID 0x0003 to the VID 0x128d (Testo). At least the
Testo 435-4 uses this, likely other gear as well.

USB: cp210x: add support for Corsair usb dongle

2014-08-06T17:07:35+00:00

commit b9326057a3d8447f5d2e74a7b521ccf21add2ec0 upstream.

Corsair USB Dongles are shipped with Corsair AXi series PSUs.
These are cp210x serial usb devices, so make driver detect these.
I have a program, that can get information from these PSUs.

Tested with 2 different dongles shipped with Corsair AX860i and
AX1200i units.

USB: ftdi_sio: fix null deref at port probe

2014-08-06T17:07:32+00:00

commit aea1ae8760314e072bf1b773521e9de5d5dda10d upstream.

Fix NULL-pointer dereference when probing an interface with no
endpoints.

These devices have two bulk endpoints per interface, but this avoids
crashing the kernel if a user forces a non-FTDI device to be probed.

Note that the iterator variable was made unsigned in order to avoid
a maybe-uninitialized compiler warning for ep_desc after the loop.

USB: io_ti: fix firmware download on big-endian machines (part 2)

2014-07-11T12:33:42+00:00

commit c03890ff5e24a4bf59059f2d179f427559b7330a upstream.

A recent patch that purported to fix firmware download on big-endian
machines failed to add the corresponding sparse annotation to the
i2c-header. This was reported by the kbuild test robot.

Adding the appropriate annotation revealed another endianess bug related
to the i2c-header Size-field in a code path that is exercised when the
firmware is actually being downloaded (and not just verified and left
untouched unless older than the firmware at hand).

This patch adds the required sparse annotation to the i2c-header and
makes sure that the Size-field is sent in little-endian byte order
during firmware download also on big-endian machines.

Note that this patch is only compile-tested, but that there is no
functional change for little-endian systems.

USB: usb_wwan: fix potential blocked I/O after resume

2014-07-11T12:33:40+00:00

commit fb7ad4f93d9f0f7d49beda32f5e7becb94b29a4d upstream.

Keep trying to submit urbs rather than bail out on first read-urb
submission error, which would also prevent I/O for any further ports
from being resumed.

Instead keep an error count, for all types of failed submissions, and
let USB core know that something went wrong.

Also make sure to always clear the suspended flag. Currently a failed
read-urb submission would prevent cached writes as well as any
subsequent writes from being submitted until next suspend-resume cycle,
something which may not even necessarily happen.

Note that USB core currently only logs an error if an interface resume
failed.

USB: usb_wwan: fix urb leak at shutdown

2014-07-11T12:33:40+00:00

commit 79eed03e77d481b55d85d1cfe5a1636a0d3897fd upstream.

The delayed-write queue was never emptied at shutdown (close), something
which could lead to leaked urbs if the port is closed before being
runtime resumed due to a write.

When this happens the output buffer would not drain on close
(closing_wait timeout), and after consecutive opens, writes could be
corrupted with previously buffered data, transfered with reduced
throughput or completely blocked.

Note that unbusy_queued_urb() was simply moved out of CONFIG_PM.
