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

2017-01-13T01:56:56+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: hub: Fix auto-remount of safely removed or ejected USB-3 devices

2017-01-13T01:56:53+00:00

[ Upstream commit 37be66767e3cae4fd16e064d8bb7f9f72bf5c045 ]

USB-3 does not have any link state that will avoid negotiating a connection
with a plugged-in cable but will signal the host when the cable is
unplugged.

For USB-3 we used to first set the link to Disabled, then to RxDdetect to
be able to detect cable connects or disconnects. But in RxDetect the
connected device is detected again and eventually enabled.

Instead set the link into U3 and disable remote wakeups for the device.
This is what Windows does, and what Alan Stern suggested.

USB: UHCI: report non-PME wakeup signalling for Intel hardware

2017-01-13T01:56:53+00:00

[ Upstream commit ccdb6be9ec6580ef69f68949ebe26e0fb58a6fb0 ]

The UHCI controllers in Intel chipsets rely on a platform-specific non-PME
mechanism for wakeup signalling.  They can generate wakeup signals even
though they don't support PME.

We need to let the USB core know this so that it will enable runtime
suspend for UHCI controllers.

usb: gadget: composite: correctly initialize ep->maxpacket

2017-01-13T01:50:07+00:00

[ Upstream commit e8f29bb719b47a234f33b0af62974d7a9521a52c ]

usb_endpoint_maxp() returns wMaxPacketSize in its
raw form. Without taking into consideration that it
also contains other bits reserved for isochronous
endpoints.

This patch fixes one occasion where this is a
problem by making sure that we initialize
ep->maxpacket only with lower 10 bits of the value
returned by usb_endpoint_maxp(). Note that seperate
patches will be necessary to audit all call sites of
usb_endpoint_maxp() and make sure that
usb_endpoint_maxp() only returns lower 10 bits of
wMaxPacketSize.

USB: serial: cp210x: fix tiocmget error handling

2016-11-26T03:57:02+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: increase ohci watchdog delay to 275 msec

2016-11-24T01:59:49+00:00

[ Upstream commit ed6d6f8f42d7302f6f9b6245f34927ec20d26c12 ]

Increase ohci watchout delay to 275 ms. Previous delay was 250 ms
with 20 ms of slack, after removing slack time some ohci controllers don't
respond in time. Logs from systems with controllers that have the
issue would show "HcDoneHead not written back; disabled"

USB: serial: fix potential NULL-dereference at probe

2016-11-24T01:59:49+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.
