mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Bug description:
  [ Impact ]

   * Systems with Dell DW5826e WWAN modems currently cannot benefit from
  USB autosuspend power management, preventing the processor from
  reaching deeper PC# states when the modem is idle.

   * Backporting upstream patch [1] that adds rules in
  hwdb.d/60-autosuspend.hwdb for Dell DW5826e WWAN modem

  [ Test Plan ]

   * DUT: Platform with Dell DW5826e WWAN modem

  $ lsusb -d 413c:8217
  Bus 004 Device 002: ID 413c:8217 Dell Computer Corp. DW5826e-eSIM Qualcomm Snapdragon X12 Global LTE-A
  $ cat /sys/bus/usb/devices/4-1/idVendor 
  413c
  $ cat /sys/bus/usb/devices/4-1/idProduct 
  8217

   1. Confirm autosuspend is not enabled before patch and is set to "on"
  in power/control

  $ cat /sys/bus/usb/devices/4-1/power/control 
  on

   2. Install patch
   3. Autosuspend is enabled, namely, set to "auto" in power/control

  $ cat power/control
  auto

  [ Where problems could occur ]

   * The modem might experience connection instability or fail to wake
  up properly from suspend.
