- * History :
- *  16/07/2002 : v1.04 -- Julien BLACHE <jb@jblache.org>
- *    + removed useless usblp_cleanup()
- *    + removed {un,}lock_kernel() as suggested on lkml
- *    + inlined clear_pipes() (used once)
- *    + inlined clear_device() (small, used twice)
- *    + removed tiglusb_find_struct() (used once, simple code)
- *    + replaced down() with down_interruptible() wherever possible
- *    + fixed double unregistering wrt devfs, causing devfs
- *      to force an oops when the device is deconnected
- *    + removed unused fields from struct tiglusb_t
+ *   1.0x, Romain & Julien: initial submit.
+ *   1.03, Greg Kroah: modifications.
+ *   1.04, Julien: clean-up & fixes; Romain: 2.4 backport.
+ *   1.05, Randy Dunlap: bug fix with the timeout parameter (divide-by-zero).
+ *   1.06, Romain: synched with 2.5, version/firmware changed (confusing).
