USB: visor: Match I330 phone more precisely

2015-06-10T17:42:17+00:00

[ Upstream commit 82ee3aeb9295c5fc37fd2ddf20f13ac2b40ec97d ]

Samsung has just released a portable USB3 SSD, coming in a very small
and nice form factor. It's USB ID is 04e8:8001, which unfortunately is
already used by the Palm Visor driver for the Samsung I330 phone cradle.
Having pl2303 or visor pick up this device ID results in conflicts with
the usb-storage driver, which handles the newly released portable USB3
SSD.

To work around this conflict, I've dug up a mailing list post [1] from a
long time ago, in which a user posts the full USB descriptor
information. The most specific value in this appears to be the interface
class, which has value 255 (0xff). Since usb-storage requires an
interface class of 0x8, I believe it's correct to disambiguate the two
devices by matching on 0xff inside visor.

usb: serial: silence all non-critical read errors

2015-04-27T21:13:47+00:00

[ Upstream commit aa8e22128b40590b291cd13512098bf258a7e6c5 ]

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.

USB: ftdi_sio: Use jtag quirk for SNAP Connect E10

2015-04-24T21:13:48+00:00

[ Upstream commit b229a0f840f774d29d8fedbf5deb344ca36b7f1a ]

This patch uses the existing CALAO Systems ftdi_8u2232c_probe in order
to avoid attaching a TTY to the JTAG port as this board is based on the
CALAO Systems reference design and needs the same fix up.

USB: keyspan_pda: add new device id

2015-04-24T21:13:47+00:00

[ Upstream commit 5e71fc8629cefae5f3c1a4f498de3fe4f631924a ]

Add USB VID/PID for Xircom PGMFHUB USB/serial component.  (The hub and SCSI
bridge on that hardware are recognized out of the box by existing drivers.)
Tested VID/PID using new_id and loopback connection and was met with
success, but that's all the testing done.

USB: serial: fix tty-device error handling at probe

2015-03-14T19:37:26+00:00

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.

USB: serial: fix potential use-after-free after failed probe

2015-03-14T19:37:26+00:00

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.

USB: serial: fix infinite wait_until_sent timeout

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.
