  this proposed patch for drivers/atm/ambassador.c atm driver for Linux
  removes one call to check_region using request_region instead

  I don't have this hardware so patch is not tested.  This patch removes
  all references to check_region in this driver.

  This is patch number 30 in a series of check_region patches I am doing as
   part of the kernel janitors project.
