  Bluetooth not working

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  == SRU Justification ==
  A regression was discovered in Bionic.  The regression was introduced by
  mainline commit f44cb4b19ed4, which then made it's way into Bionic in
  4.15.0-14 as commit c91729972ac6 via stable updates.

  This regression is fixed by mainline commit 803cdb8ce584.  Commit
  803cdb8ce584 was also cc'd to stable.  However, it has not landed in
  upstream stable 4.15 or Bionic.

  == Fix ==
  803cdb8ce584 ("Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 

  == Regression Potential ==
  Low.  This fix has also been cc'd to upstream stable, so it has had
  additonal upstream review.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
  The bug reporter states the test kernel resolved the bug.

  I've installed the Ubuntu Bionic Beta 2 and everything works fine but
  the bluetooth (perfectly working with Xenial). In bluetooth control
  panel the slider is impossible to move to "on".
