USB: visor: Match I330 phone more precisely

2015-06-03T09:33:10+00:00

commit 82ee3aeb9295c5fc37fd2ddf20f13ac2b40ec97d upstream.

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: ftdi_sio: Use jtag quirk for SNAP Connect E10

2015-04-22T06:58:37+00:00

commit b229a0f840f774d29d8fedbf5deb344ca36b7f1a upstream.

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: zte_ev: fix removed PIDs

2015-04-09T12:13:33+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: serial: fix tty-device error handling at probe

2015-03-12T16:31:18+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

2015-03-12T16:31:18+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

2015-03-12T16:31:17+00:00

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.
