commit eaa496ffaaf19591fe471a36cef366146eeb9153 upstream.

ep->mult is supposed to be set to Isochronous and
Interrupt Endapoint's multiplier value. This value
is computed from different places depending on the
link speed.

If we're dealing with HighSpeed, then it's part of
bits [12:11] of wMaxPacketSize. This case wasn't
taken into consideration before.

While at that, also make sure the ep->mult defaults
to one so drivers can use it unconditionally and
assume they'll never multiply ep->maxpacket to zero.

USB: UHCI: report non-PME wakeup signalling for Intel hardware 2017-01-06T10:16:08+00:00 Alan Stern stern@rowland.harvard.edu 2016-10-21T20:49:07+00:00 cbb2a2563587fe344156b37b614d168d6faa4238 commit ccdb6be9ec6580ef69f68949ebe26e0fb58a6fb0 upstream. 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 2017-01-06T10:16:08+00:00 Felipe Balbi felipe.balbi@linux.intel.com 2016-09-28T07:38:11+00:00 8ede2d7908aa9970979ef5e5fc95d3d69976d353 commit e8f29bb719b47a234f33b0af62974d7a9521a52c upstream. 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: hub: Fix auto-remount of safely removed or ejected USB-3 devices 2017-01-06T10:16:07+00:00 Mathias Nyman mathias.nyman@linux.intel.com 2016-11-17T09:14:14+00:00 747b31526369e700feac40e0cbc7d9b610e29649 commit 37be66767e3cae4fd16e064d8bb7f9f72bf5c045 upstream. 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.
