Pull IDE updates from David Miller:
 "Just a few small things:

   1) module_platform_driver_probe() conversions from Jingoo Han.

   2) module_pci_driver() conversion from Libo Chen.

   3) PIO size calculation fix from Steven J Hill"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/ide:
  ide: Fix IDE PIO size calculation
  drivers/ide/delkin_cb: Convert to module_pci_driver
  ide: gayle: use module_platform_driver_probe()
  ide: tx4939ide: use module_platform_driver_probe()
  ide: tx4938ide: use module_platform_driver_probe()
