USB: serial: cp210x: fix tiocmget error handling

2016-11-24T03:56:56+00:00

[ Upstream commit de24e0a108bc48062e1c7acaa97014bce32a919f ]

The current tiocmget implementation would fail to report errors up the
stack and instead leaked a few bits from the stack as a mask of
modem-status flags.

USB: serial: fix potential NULL-dereference at probe

2016-11-24T02:54:57+00:00

[ Upstream commit 126d26f66d9890a69158812a6caa248c05359daa ]

Make sure we have at least one port before attempting to register a
console.

Currently, at least one driver binds to a "dummy" interface and requests
zero ports for it. Should such an interface also lack endpoints, we get
a NULL-deref during probe.

[ Upstream commit ca006f785fbfd7a5c901900bd3fe2b26e946a1ee ]

This adds support to ftdi_sio for the Infineon TriBoard TC2X7
engineering board for first-generation Aurix SoCs with Tricore CPUs.
Mere addition of the device IDs does the job.

[ Upstream commit 647024a7df36014bbc4479d92d88e6b77c0afcf6 ]

udriver struct allocated by kzalloc() will not be freed
if usb_register() and next calls fail. This patch fixes this
by adding one more step with kfree(udriver) in error path.

USB: serial: option: add support for Telit LE920A4

2016-08-31T23:26:03+00:00

[ Upstream commit 01d7956b58e644ea0d2e8d9340c5727a8fc39d70 ]

This patch adds a set of compositions for Telit LE920A4.

Compositions in short are:

0x1207: tty + tty
0x1208: tty + adb + tty + tty
0x1211: tty + adb + ecm
0x1212: tty + adb
0x1213: ecm + tty
0x1214: tty + adb + ecm + tty

telit_le922_blacklist_usbcfg3 is reused for compositions 0x1211
and 0x1214 due to the same interfaces positions.
