Instead of dereferencing pointer and put values on stack we could use nice
%*phC specifier.

Hub-initiated LPM is not good for USB communications devices. Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.
If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data. Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.
The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host. In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.
Set the disable_hub_initiated_lpm flag for for all USB communications
drivers. I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

This converts the drivers in drivers/net/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

Make sure that the 'static' keywork is at the beginning of declaration
for drivers/net/usb/kalmia.c
This gets rid of warnings like
warning: ‘static’ is not at beginning of declaration
when building with -Wold-style-declaration (and/or -Wextra which also
enables it).

Introducing driver for the network port of Samsung Kalmia based USB LTE modems.
It has also an ACM interface that previous patches associates with the "option"
module. To access those interfaces, the modem must first be switched from modem
mode using a tool like usb_modeswitch.
As the proprietary protocol has been discovered by watching the MS Windows driver
behavior, there might be errors in the protocol handling, but stable and fast
connection has been established for hours with Norwegian operator NetCom that
distributes this modem with their LTE/4G subscription.
More and updated information about how to use this driver is available here:
