Trusty update to 3.16.7-ckt21 stable release

[Luis Henriques]

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from Linus' tree or in a minimally
       backported form of that patch. The 3.16.7-ckt21 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://kernel.ubuntu.com/ubuntu/linux.git

Hi new to launchpad ... please bear any transgressions coming from a noob !

My OS : UbuntuGnome 14.04 LTS
kernel : 3.13.0-109-generic
HP lt2523 (Novatel E371) WWAN card
03f0:421d Hewlett-Packard

My OS does not detect this lte module. however the same works fine on Windows 10.

Thanks to some great folks at http://www.draisberghof.de/usb_modeswitch/ ... who helped me have this device up and running on my OS(manually), as per their observations it seems that the device ID of this Novatel E371 rebranded by HP is not part of some list in the kernel chain used in my 14.04 lts gnome flavor.

I have to run the following set of commands every time i boot into my laptop to use this module.

modprobe option
modprobe qmi_wwan
echo 03f0 421d > /sys/bus/usb-serial/drivers/option1/new_id
echo 03f0 421d > /sys/bus/usb/drivers/cdc_ether/new_id
echo 03f0 421d > /sys/bus/usb/drivers/qmi_wwan/new_id
echo 1-1.5:1.6 > /sys/bus/usb/drivers/cdc_ether/unbind
echo 1-1.5:1.6 > /sys/bus/usb/drivers/qmi_wwan/bind
restart modemmanager
sleep 30
restart network-manager

the device ID is already added to kernel chain 4.9.8 as per this thread ...

http://marc.info/?t=148525137300001&r=1&w=2

the technical aspects are listed out in the above thread.
Can somebody here apply this change to the kernel chain my OS is using ?

thanks.

if this is a wrong thread/subject ... please let me know ... i'll start a fresh bug report
thanks.
