      firewire: fix crash in automatic module unloading · 855c603d

      "modprobe firewire-ohci; sleep .1; modprobe -r firewire-ohci" used to
      result in crashes like this:

      Note that this crash happened _after_ firewire-core was unloaded.  The
      shared workqueue tried to run firewire-core's device initialization jobs
      or similar jobs.
      
      The fix makes sure that firewire-ohci and hence firewire-core is not
      unloaded before all device shutdown jobs have been completed.  This is
      determined by the count of device initializations minus device releases.
      
      Also skip useless retries in the node initialization job if the node is
      to be shut down.

      Driver core: change add_uevent_var to use a struct · 7eff2e7a
      Kay Sievers authored
      This changes the uevent buffer functions to use a struct instead of a
      long list of parameters. It does no longer require the caller to do the
      proper buffer termination and size accounting, which is currently wrong
      in some places. It fixes a known bug where parts of the uevent
      environment are overwritten because of wrong index calculations.
      
      Many thanks to Mathieu Desnoyers for finding bugs and improving the
      error handling.
