Title:
  DKMS 2.0.17.4 uninstalls wrong file

Status in “dkms” package in Ubuntu:
  Fix Released

Bug description:
  DKMS 2.0.17.4 and earlier has a bug whereby when running 'dkms
  uninstall', it will not delete the module previously installed into
  /lib/modules/$kernelver/updates/dkms/  but will instead delete the
  module at /lib/modules/$kernelver/kernel/drivers/... which is
  incorrect.  DKMS 2.0.17.5 corrects this.

  In addition, DKMS 2.0.17.5 invokes depmod after uninstalling a module
  so stale data is not retained, and invokes udevtrigger after
  installing a module for the currently-running kernel in case that
  module now enables a new device which udev should be aware of.

  DKMS 2.0.17.5 is available in REVU at
  http://revu.tauware.de/details.py?upid=376
