784506cbdd ide: sanitize handling of IDE_HFLAG_NO_SET_MODE host flag
* Check for IDE_HFLAG_NO_SET_MODE host flag in ide_set_pio(),
  ide_set_[pio,dma]_mode(), ide_set_xfer_rate() and set_pio_mode().

* Remove no longer needed IDE_HFLAG_NO_SET_MODE host flag checking
  from ide_tune_dma().

* Remove superfluous ->set_pio_mode checking from do_special().

This is a part of preparations for adding 'struct ide_port_ops'.

4764b68405 sis5513: fail early for unsupported chipsets
* Factor out chipset family detection from init_chipset_sis5513()
  to sis_find_family().

* Use sis_find_family() in sis5513_init_one() to fail early if the
  chipset is unsupported.

* Keep a local copy sis5513_chipset in sis5513_init_one()
  and set .udma_mask according to chipset family.

* Remove no longer need ->ultra_mask setting from init_hwif_sis5513().

eb7a07e8d6 it821x: fix kzalloc() failure handling
Allocate 'struct it821x_dev' objects for both ports in it821x_init_one().

Fixes potential OOPS in it821x_quirkproc() (uses 'itdev' unconditionally)
and other problems ('itdev' is needed for correct operation of the driver).

79472b6ea9 qd65xx: use IDE_HFLAG_SINGLE host flag
* Set IDE_HFLAG_SINGLE host flag in qd_probe() for QD6500 and QD6580
  with the second port disabled.

* Check for IDE_HFLAG_SINGLE in qd6580_port_init_devs() instead of
  using cached value of QD6580 Control register.

* Don't cache QD6580 Control register value in hwif->config_data
  (bits 8-15) and remove no longer needed QD_CONTROL() macro.

* Cache QD65xx base address in hwif->config_data (bits 8-15)
  instead of hwif->select_data.

* Set hwif->config_data in qd_probe() and remove qd_setup() helper.
