      Staging: Panel: prevent driver from calling misc_deregister twice on same ressource · 0b0595bf
      Peter Huewe authored
      This patch prevents the driver from calling misc_deregister twice on the same
      ressouce when unloading the driver.
      Unloading the driver without this patch results in a Kernel BUG like this:
      Panel driver version 0.9.5 registered on parport0 (io=0x378).
      BUG: unable to handle kernel paging request at 0000000000100108

      This patch fixes this issue, although maybe not in the best way possible :)
