2f40c9b0b6 ide: fix kmalloc() failure handling in ide_driveid_update()
* Doing kmalloc() in the middle of command execution is not only ugly
  but leaves drive waiting to send data on kmalloc() failure.  Fix it.

While at it:

* Unify error code paths.

* Fixup error message to be more useful and add missing KERN_ERR level.

* Rename 'stat' variable to 's'.

2ed0ef543a ide: fix ->init_chipset method to return 'int' value
* Return 0 instead of dev->irq in ->init_chipset implementations.

* Fix ->init_chipset method to return 'int' value instead of
  'unsigned int' one.

This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.

Controller with Compact Flash True IDE Mode logic.

Driver have to switch 8/16 bit bus width when accessing Task Tile or Data
Register. Moreover some extra things need to be done when setting PIO mode.
Only PIO mode is used, hardware have no DMA support. If interrupt line is
connected through GPIO extra quirk is needed to cope with fake interrupts.
