[PATCH 0/4][trusty] iwlwifi: Support for collecting firmware state dumps on errors

[Seth Forshee]

Intel has requested that we pick up a patch from wireless-next which
collects firmware state dumps to assist with debugging firmware errors.
What follows is a backport of the patch from 3.13 plus a few additional
improvements.

This is also going to require a udev rule to collect the dumps and
apport changes to attach them to bug reports, both of which I'm
currently working on.

Thanks,
Seth

    dump logs

  UBUNTU: SAUCE: iwlwifi: mvm: Free sram dump immediately after using it
  UBUNTU: SAUCE: iwlwifi: mvm: Only notify userspace of fw error dump
    when one is created
  UBUNTU: SAUCE: iwlwifi: mvm: Don't create fw error dump if there's
    nothing to dump
