   1 /*
   2  * USB IBM C-It Video Camera driver
   3  *
   4  * Supports Xirlink C-It Video Camera, IBM PC Camera,
   5  * IBM NetCamera and Veo Stingray.
   6  *
   7  * This driver is based on earlier work of:
   8  *
   9  * (C) Copyright 1999 Johannes Erdfelt
  10  * (C) Copyright 1999 Randy Dunlap
  11  *
  12  * 5/24/00 Removed optional (and unnecessary) locking of the driver while
  13  * the device remains plugged in. Corrected race conditions in ibmcam_open
  14  * and ibmcam_probe() routines using this as a guideline:
  15  *
  16  * (2) The big kernel lock is automatically released when a process sleeps
  17  *   in the kernel and is automatically reacquired on reschedule if the
  18  *   process had the lock originally.  Any code that can be compiled as
  19  *   a module and is entered with the big kernel lock held *MUST*
  20  *   increment the use count to activate the indirect module protection
  21  *   before doing anything that might sleep.
  22  *
  23  *   In practice, this means that all routines that live in modules and
  24  *   are invoked under the big kernel lock should do MOD_INC_USE_COUNT
  25  *   as their very first action.  And all failure paths from that
  26  *   routine must do MOD_DEC_USE_COUNT before returning.
