    3.0-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Stanislaw Gruszka <sgruszka@redhat.com>

    commit 2e2a41d6ca07d1b2aa67015c35fd80701c98e867 upstream.

    iwlegacy version of fix:

    commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc

    iwlagn: fix command queue timeout

    If the command queue is constantly busy,
    which can happen in P2P, the hangcheck
    timer will frequently find a command in
    it and will eventually reset the device
    because nothing sets the timestamp for
    this queue when commands are processed.

    Fix this by setting the timestamp when
    a command completes.

    iwlegacy does not support P2P, but this patch fix possible
    unneeded hardware resets, hence is needed.
