Pull IDE updates from David Miller:

 1) Fix mem region name in tx4949ide driver, from Christophe JAILLET.

 2) Make drive->dn read only, it should not be changeable by users. From
    Dan Carpenter.

 3) Several cast fixups from Krzysztof Kozlowski.

There is also going to be a removal of a now unused IDE driver, but that
will come via the MIPS tree.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/ide:
  ide: make drive->dn read only
  ide: serverworks: potential overflow in svwks_set_pio_mode()
  cmd64x: potential buffer overflow in cmd64x_program_timings()
  ide: remove unneeded header include path to drivers/ide
  ide: qd65xx: Fix cast to pointer from integer of different size
  ide: ht6560b: Fix cast to pointer from integer of different size
  ide: remove set but not used variable 'hwif'
  ide: remove unnecessary touch_softlockup_watchdog
  ide: tx4939ide: Fix the name used in a 'devm_request_mem_region()' call
  ide: Use dev_get_drvdata where possible
