[PATCH] remove check_region from drivers_isdn_hisax_asuscom.c

  This patch for drivers/isdn/hisax/asuscom.c isdn 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 26 in a series of check_region patches I am doing as
  part of the kernel janitors project.
