USB: serial: option: add support for Telit LE922A PIDs 0x1040, 0x1041

2017-01-15T14:49:51+00:00

[ Upstream commit 5b09eff0c379002527ad72ea5ea38f25da8a8650 ]

This patch adds support for PIDs 0x1040, 0x1041 of Telit LE922A.

Since the interface positions are the same than the ones used
for other Telit compositions, previous defined blacklists are used.

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.
