When applying commit 7d26b58 (fix failure path in

fix array
Non-hub device has no child, and even a real USB hub has ports far
less than USB_MAXCHILDREN, so there is no need using a fix array for
child devices, just allocate it dynamically according real port
number.

In the past, the room_on_ring() check was implemented by walking all over
the ring, which is wasteful and complicated.
Count the number of free TRBs instead. The free TRBs number should be

of a set dequeue pointer command.

The latest released errata for USB2.0 ECN LPM adds new fields to USB2.0
extension descriptor, defines two BESL values for device: baseline BESL
and deep BESL. Baseline BESL value communicates a nominal power savings
design point and the deep BESL value communicates a significant power
savings design point.
If device indicates BESL value, driver will use a value count in both
host BESL and device BESL. Use baseline BESL value as default.

Adding the Pantech UML290 and all non-QDL Gobi device IDs from the
qcserial driver now that we have support for shared net/QMI USB
interfaces. Most of these are not yet tested with this driver, but
should be mostly identical to tested devices, except for device IDs.
Gobi devices provide several different interfaces (serial/net/other)
using the exact same class, subclass and protocol values. This driver
will only support the net/QMI function while there are other drivers
supporting other device functions. The net/QMI interface number may
also differ from device to device. It has been noted that all the
other interfaces have additional functional descriptors, so we use that
to detect the interface supported by this driver.

Use the new cdc-wdm subdriver interface to create a device management
device even for USB devices having a single combined QMI/wwan USB
interface with three endpoints (int, bulk in, bulk out) instead of
separate data and control interfaces.
Some Huawei devices can be switched to a single interface mode for
use with other operating systems than Linux. This adds support
for these devices when they run in such non-Linux modes.

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
near standard CDC ECM interfaces in addition to the usual serial
interfaces. The Huawei E392/E398 are examples of such devices.
These typically cannot be fully configured using AT commands
over a serial interface. It is necessary to speak the proprietary
Qualcomm MSM Interface (QMI) protocol to the device to enable the
ethernet proxy functionality.
The devices embed the QMI protocol in CDC on the control interface,
using standard CDC commands and notifications. The do not otherwise
use CDC commands for the ethernet function. This driver does
therefore not need access to any other aspects of the control
interface than the descriptors attached to it.
Another driver, cdc-wdm, will provide userspace access to the
QMI protocol independently of this driver. To facilitate this,
this driver avoids binding to the control interface, and uses
only the associated data interface after parsing the common CDC
functional descriptors on the control interface.
You will want both the cdc-wdm and option drivers as companions to
this driver, to have full access to all interfaces and protocols
exported by the device.

This driver can be used as a subdriver of another USB driver, allowing
it to export a Device Managment interface consisting of a single interrupt
endpoint with no dedicated USB interface.
Some devices provide a Device Management function combined with a wwan
function in a single USB interface having three endpoints (bulk in/out
+ interrupt). If the interrupt endpoint is used exclusively for DM
notifications, then this driver can support that as a subdriver
provided that the wwan driver calls the appropriate entry points on
probe, suspend, resume, pre_reset, post_reset and disconnect.
The main driver must have full control over all interface related
settings, including the needs_remote_wakeup flag. A manage_power
function must be provided by the main driver.
A manage_power stub doing direct flag manipulation is used in normal
driver mode.
