<id>urn:sha1:2419f30a4a4fcaa5f35111563b4c61f1b2b26841</id>
<content type='text'>
As commented in the struct's definition there shouldn't be anything
underneath its 'priv[0]' member as it would break some macros.

The patch converts the broken_suspend into a bit-field and relocates it
next to to the rest of bit-fields.

<title>xhci: Don't prevent USB2 bus suspend in state check intended for USB3 only</title>

<id>urn:sha1:45f750c16cae3625014c14c77bd9005eda975d35</id>
<content type='text'>
The code to prevent a bus suspend if a USB3 port was still in link training
also reacted to USB2 port polling state.
This caused bus suspend to busyloop in some cases.
USB2 polling state is different from USB3, and should not prevent bus
suspend.

Limit the USB3 link training state check to USB3 root hub ports only.
The origial commit went to stable so this need to be applied there as well

The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem.

The interface with protocol 0x16 is "CDC ECM &amp; NCM" according to the *.inf
files included with the Windows driver. Attaching the option driver to it
doesn't result in a /dev/ttyUSB* device being created, so I've excluded it.
Note that it is also excluded for corresponding Huawei-branded devices, cf.
commit d544db293a44 ("USB: support new huawei devices in option.c").

Don't allow USB3 U1 or U2 if the latency to wake up from the U-state
reaches the service interval for a periodic endpoint.

This is according to xhci 1.1 specification section 4.23.5.2 extra note:

"Software shall ensure that a device is prevented from entering a U-state
 where its worst case exit latency approaches the ESIT."

Allowing too long exit latencies for periodic endpoint confuses xHC
internal scheduling, and new devices may fail to enumerate with a
"Not enough bandwidth for new device state" error from the host.
