14 * Thomas Sailer : ioctl code reworked (vmalloc/vfree removed)
15 * Sergey Smitienko : ensoniq p'n'p support
16 * Christoph Hellwig : adapted to module_init/module_exit
17 * Bartlomiej Zolnierkiewicz : added __init to attach_sscape()
18 * Chris Rankin : Specify that this module owns the coprocessor
19 * Arnaldo C. de Melo : added missing restore_flags in sscape_pnp_upload_file
