  Scanner not detected over wifi since after 3.13.0-68

Status in linux package in Ubuntu:

Bug description:
  Please see http://ubuntuforums.org/showthread.php?t=2306464 for
  details.  I'm running 64-bit 14.04 LTS ubuntu.

  When I boot my PC into 3.13.0-68-generic (via the 'ubuntu advanced'
  menu item in grub) I can detect my scanner over wifi using scangearmp.
  However since 3.13.0-70-generic I have not been able to detect my
  scanner over wifi.  My current kernel is 3.13.0-74-generic.  Therefore
  I suspect a regression has occurred between 3.13.0-68-generic and

  Scanner *is* detected by scangearmp over wifi and it scans documents as expected in this version:
  uname -a
  Linux zorro 3.13.0-68-generic #111-Ubuntu SMP Fri Nov 6 18:17:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

  But scanner is *not* detected by scangearmp in this version or later:
  Linux zorro 3.13.0-70-generic #113-Ubuntu SMP Mon Nov 16 18:34:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

  Note that this happened before some time ago. i.e., The scanner was
  detected over wifi, then not, then it was again some time later. Then
  this latest break occurred again. I suspect successive updates are
  fixing or breaking the detection accordingly.

  $ dpkg -l | grep scangear
  ii  scangearmp-common                                     2.20-1                                              amd64        ScanGear MP for Linux.
  ii  scangearmp-mg7100series                               2.20-1                                              amd64        ScanGear MP for Linux.

  Device is Canon Pixma MG7150 (combined printer, scanner, copier). Note
  the printer works fine over wifi; only the scanner is affected.

  I can see from the changelog at
  that many changes went into 3.13.0-69.112 but it's not obvious to me
  which of these might have caused the regression.
