[PATCH] remove check_region from drivers_isdn_hisax_w6692.c

  This patch for driver drivers/isdn/hisax/bkm_a8.c for Linux removes
  one call to check_region using request_region instead.

  I don't have this hardware so I hope I got it right.  This patch
  removes all references to check_region in this driver.

  This is patch number 23 in a series of check_region patches I am doing as
  part of the kernel janitors project.
