[PATCH] remove check_region in drivers_isdn_hisax_mic.c

  This patch for drivers/isdn/hisax/mic.c driver 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 18 in a series of check_region patches I am doing as
  part of the kernel janitors project.
